+
+## API
+
+### fromObject(obj)
+
+Returns source map converter from given object.
+
+### fromJSON(json)
+
+Returns source map converter from given json string.
+
+### fromBase64(base64)
+
+Returns source map converter from given base64 encoded json string.
+
+### fromComment(comment)
+
+Returns source map converter from given base64 encoded json string prefixed with `//# sourceMappingURL=...`.
+
+### fromMapFileComment(comment, mapFileDir)
+
+Returns source map converter from given `filename` by parsing `//# sourceMappingURL=filename`.
+
+`filename` must point to a file that is found inside the `mapFileDir`. Most tools store this file right next to the
+generated file, i.e. the one containing the source map.
+
+### fromSource(source)
+
+Finds last sourcemap comment in file and returns source map converter or returns null if no source map comment was found.
+
+### fromMapFileSource(source, mapFileDir)
+
+Finds last sourcemap comment in file and returns source map converter or returns null if no source map comment was
+found.
+
+The sourcemap will be read from the map file found by parsing `# sourceMappingURL=file` comment. For more info see
+fromMapFileComment.
+
+### toObject()
+
+Returns a copy of the underlying source map.
+
+### toJSON([space])
+
+Converts source map to json string. If `space` is given (optional), this will be passed to
+[JSON.stringify](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/JSON/stringify) when the
+JSON string is generated.
+
+### toBase64()
+
+Converts source map to base64 encoded json string.
+
+### toComment([options])
+
+Converts source map to an inline comment that can be appended to the source-file.
+
+By default, the comment is formatted like: `//# sourceMappingURL=...`, which you would
+normally see in a JS source file.
+
+When `options.multiline == true`, the comment is formatted like: `/*# sourceMappingURL=... */`, which you would find in a CSS source file.
+
+### addProperty(key, value)
+
+Adds given property to the source map. Throws an error if property already exists.
+
+### setProperty(key, value)
+
+Sets given property to the source map. If property doesn't exist it is added, otherwise its value is updated.
+
+### getProperty(key)
+
+Gets given property of the source map.
+
+### removeComments(src)
+
+Returns `src` with all source map comments removed
+
+### removeMapFileComments(src)
+
+Returns `src` with all source map comments pointing to map files removed.
+
+### commentRegex
+
+Provides __a fresh__ RegExp each time it is accessed. Can be used to find source map comments.
+
+### mapFileCommentRegex
+
+Provides __a fresh__ RegExp each time it is accessed. Can be used to find source map comments pointing to map files.
+
+### generateMapFileComment(file, [options])
+
+Returns a comment that links to an external source map via `file`.
+
+By default, the comment is formatted like: `//# sourceMappingURL=...`, which you would normally see in a JS source file.
+
+When `options.multiline == true`, the comment is formatted like: `/*# sourceMappingURL=... */`, which you would find in a CSS source file.

+Implementation of function.prototype.bind
+
+## Example
+
+I mainly do this for unit tests I run on phantomjs.
+PhantomJS does not have Function.prototype.bind :(
+
+```js
+Function.prototype.bind = require("function-bind")
+```
+
+## Installation
+
+`npm install function-bind`

+# gensync
+
+This module allows for developers to write common code that can share
+implementation details, hiding whether an underlying request happens
+synchronously or asynchronously. This is in contrast with many current Node
+APIs which explicitly implement the same API twice, once with calls to
+synchronous functions, and once with asynchronous functions.
+
+Take for example `fs.readFile` and `fs.readFileSync`, if you're writing an API
+that loads a file and then performs a synchronous operation on the data, it
+can be frustrating to maintain two parallel functions.
+
+
+## Example
+
+```js
+const fs = require("fs");
+const gensync = require("gensync");
+
+const readFile = gensync({
+  sync: fs.readFileSync,
+  errback: fs.readFile,
+});
+
+const myOperation = gensync(function* (filename) {
+  const code = yield* readFile(filename, "utf8");
+
+  return "// some custom prefix\n" + code;
+});
+
+// Load and add the prefix synchronously:
+const result = myOperation.sync("./some-file.js");
+
+// Load and add the prefix asynchronously with promises:
+myOperation.async("./some-file.js").then(result => {
+
+});
+
+// Load and add the prefix asynchronously with promises:
+myOperation.errback("./some-file.js", (err, result) => {
+
+});
+```
+
+This could even be exposed as your official API by doing
+```js
+// Using the common 'Sync' suffix for sync functions, and 'Async' suffix for
+// promise-returning versions.
+exports.myOperationSync = myOperation.sync;
+exports.myOperationAsync = myOperation.async;
+exports.myOperation = myOperation.errback;
+```
+or potentially expose one of the async versions as the default, with a
+`.sync` property on the function to expose the synchronous version.
+```js
+module.exports = myOperation.errback;
+module.exports.sync = myOperation.sync;
+````
+
+
+## API
+
+### gensync(generatorFnOrOptions)
+
+Returns a function that can be "await"-ed in another `gensync` generator
+function, or executed via
+
+* `.sync(...args)` - Returns the computed value, or throws.
+* `.async(...args)` - Returns a promise for the computed value.
+* `.errback(...args, (err, result) => {})` - Calls the callback with the computed value, or error.
+
+
+#### Passed a generator
+
+Wraps the generator to populate the `.sync`/`.async`/`.errback` helpers above to
+allow for evaluation of the generator for the final value.
+
+##### Example
+
+```js
+const readFile = function* () {
+  return 42;
+};
+
+const readFileAndMore = gensync(function* (){
+  const val = yield* readFile();
+  return 42 + val;
+});
+
+// In general cases
+const code = readFileAndMore.sync("./file.js", "utf8");
+readFileAndMore.async("./file.js", "utf8").then(code => {})
+readFileAndMore.errback("./file.js", "utf8", (err, code) => {});
+
+// In a generator being called indirectly with .sync/.async/.errback
+const code = yield* readFileAndMore("./file.js", "utf8");
+```
+
+
+#### Passed an options object
+
+* `opts.sync`
+
+  Example: `(...args) => 4`
+
+  A function that will be called when `.sync()` is called on the `gensync()`
+  result, or when the result is passed to `yield*` in another generator that
+  is being run synchronously.
+
+  Also called for `.async()` calls if no async handlers are provided.
+
+* `opts.async`
+
+  Example: `async (...args) => 4`
+
+  A function that will be called when `.async()` or `.errback()` is called on
+  the `gensync()` result, or when the result is passed to `yield*` in another
+  generator that is being run asynchronously.
+
+* `opts.errback`
+
+  Example: `(...args, cb) => cb(null, 4)`
+
+  A function that will be called when `.async()` or `.errback()` is called on
+  the `gensync()` result, or when the result is passed to `yield*` in another
+  generator that is being run asynchronously.
+
+  This option allows for simpler compatibility with many existing Node APIs,
+  and also avoids introducing the extra even loop turns that promises introduce
+  to access the result value.
+
+* `opts.name`
+
+  Example: `"readFile"`
+
+  A string name to apply to the returned function. If no value is provided,
+  the name of `errback`/`async`/`sync` functions will be used, with any
+  `Sync` or `Async` suffix stripped off. If the callback is simply named
+  with ES6 inference (same name as the options property), the name is ignored.
+
+* `opts.arity`
+
+  Example: `4`
+
+  A number for the length to set on the returned function. If no value
+  is provided, the length will be carried over from the `sync` function's
+  `length` value.
+
+##### Example
+
+```js
+const readFile = gensync({
+  sync: fs.readFileSync,
+  errback: fs.readFile,
+});
+
+const code = readFile.sync("./file.js", "utf8");
+readFile.async("./file.js", "utf8").then(code => {})
+readFile.errback("./file.js", "utf8", (err, code) => {});
+```
+
+
+### gensync.all(iterable)
+
+`Promise.all`-like combinator that works with an iterable of generator objects
+that could be passed to `yield*` within a gensync generator.
+
+#### Example
+
+```js
+const loadFiles = gensync(function* () {
+  return yield* gensync.all([
+    readFile("./one.js"),
+    readFile("./two.js"),
+    readFile("./three.js"),
+  ]);
+});
+```
+
+
+### gensync.race(iterable)
+
+`Promise.race`-like combinator that works with an iterable of generator objects
+that could be passed to `yield*` within a gensync generator.
+
+#### Example
+
+```js
+const loadFiles = gensync(function* () {
+  return yield* gensync.race([
+    readFile("./one.js"),
+    readFile("./two.js"),
+    readFile("./three.js"),
+  ]);
+});
+```

+# JSON5 – JSON for Humans
+
+[![Build Status](https://travis-ci.org/json5/json5.svg)][Build Status]
+[![Coverage
+Status](https://coveralls.io/repos/github/json5/json5/badge.svg)][Coverage
+Status]
+
+The JSON5 Data Interchange Format (JSON5) is a superset of [JSON] that aims to
+alleviate some of the limitations of JSON by expanding its syntax to include
+some productions from [ECMAScript 5.1].
+
+This JavaScript library is the official reference implementation for JSON5
+parsing and serialization libraries.
+
+[Build Status]: https://travis-ci.org/json5/json5
+
+[Coverage Status]: https://coveralls.io/github/json5/json5
+
+[JSON]: https://tools.ietf.org/html/rfc7159
+
+[ECMAScript 5.1]: https://www.ecma-international.org/ecma-262/5.1/
+
+## Summary of Features
+The following ECMAScript 5.1 features, which are not supported in JSON, have
+been extended to JSON5.
+
+### Objects
+- Object keys may be an ECMAScript 5.1 _[IdentifierName]_.
+- Objects may have a single trailing comma.
+
+### Arrays
+- Arrays may have a single trailing comma.
+
+### Strings
+- Strings may be single quoted.
+- Strings may span multiple lines by escaping new line characters.
+- Strings may include character escapes.
+
+### Numbers
+- Numbers may be hexadecimal.
+- Numbers may have a leading or trailing decimal point.
+- Numbers may be [IEEE 754] positive infinity, negative infinity, and NaN.
+- Numbers may begin with an explicit plus sign.
+
+### Comments
+- Single and multi-line comments are allowed.
+
+### White Space
+- Additional white space characters are allowed.
+
+[IdentifierName]: https://www.ecma-international.org/ecma-262/5.1/#sec-7.6
+
+[IEEE 754]: http://ieeexplore.ieee.org/servlet/opac?punumber=4610933
+
+## Short Example
+```js
+{
+  // comments
+  unquoted: 'and you can quote me on that',
+  singleQuotes: 'I can use "double quotes" here',
+  lineBreaks: "Look, Mom! \
+No \\n's!",
+  hexadecimal: 0xdecaf,
+  leadingDecimalPoint: .8675309, andTrailing: 8675309.,
+  positiveSign: +1,
+  trailingComma: 'in objects', andIn: ['arrays',],
+  "backwardsCompatible": "with JSON",
+}
+```
+
+## Specification
+For a detailed explanation of the JSON5 format, please read the [official
+specification](https://json5.github.io/json5-spec/).
+
+## Installation
+### Node.js
+```sh
+npm install json5
+```
+
+```js
+const JSON5 = require('json5')
+```

+```html
+<script src="https://unpkg.com/json5@^2.0.0/dist/index.min.js"></script>
+```
+
+This will create a global `JSON5` variable.
+
+## API
+The JSON5 API is compatible with the [JSON API].
+
+[JSON API]:
+https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON
+
+### JSON5.parse()
+Parses a JSON5 string, constructing the JavaScript value or object described by
+the string. An optional reviver function can be provided to perform a
+transformation on the resulting object before it is returned.
+
+#### Syntax
+    JSON5.parse(text[, reviver])
+
+#### Parameters
+- `text`: The string to parse as JSON5.
+- `reviver`: If a function, this prescribes how the value originally produced by
+  parsing is transformed, before being returned.
+
+#### Return value
+The object corresponding to the given JSON5 text.
+
+### JSON5.stringify()
+Converts a JavaScript value to a JSON5 string, optionally replacing values if a
+replacer function is specified, or optionally including only the specified
+properties if a replacer array is specified.
+
+#### Syntax
+    JSON5.stringify(value[, replacer[, space]])
+    JSON5.stringify(value[, options])
+
+#### Parameters
+- `value`: The value to convert to a JSON5 string.
+- `replacer`: A function that alters the behavior of the stringification
+  process, or an array of String and Number objects that serve as a whitelist
+  for selecting/filtering the properties of the value object to be included in
+  the JSON5 string. If this value is null or not provided, all properties of the
+  object are included in the resulting JSON5 string.
+- `space`: A String or Number object that's used to insert white space into the
+  output JSON5 string for readability purposes. If this is a Number, it
+  indicates the number of space characters to use as white space; this number is
+  capped at 10 (if it is greater, the value is just 10). Values less than 1
+  indicate that no space should be used. If this is a String, the string (or the
+  first 10 characters of the string, if it's longer than that) is used as white
+  space. If this parameter is not provided (or is null), no white space is used.
+  If white space is used, trailing commas will be used in objects and arrays.
+- `options`: An object with the following properties:
+  - `replacer`: Same as the `replacer` parameter.
+  - `space`: Same as the `space` parameter.
+  - `quote`: A String representing the quote character to use when serializing
+    strings.
+
+#### Return value
+A JSON5 string representing the value.
+
+### Node.js `require()` JSON5 files
+When using Node.js, you can `require()` JSON5 files by adding the following
+statement.
+
+```js
+require('json5/lib/register')
+```
+
+Then you can load a JSON5 file with a Node.js `require()` statement. For
+example:
+
+```js
+const config = require('./config.json5')
+```
+
+## CLI
+Since JSON is more widely used than JSON5, this package includes a CLI for
+converting JSON5 to JSON and for validating the syntax of JSON5 documents.
+
+### Installation
+```sh
+npm install --global json5
+```
+
+### Usage
+```sh
+json5 [options] <file>
+```
+
+If `<file>` is not provided, then STDIN is used.
+
+#### Options:
+- `-s`, `--space`: The number of spaces to indent or `t` for tabs
+- `-o`, `--out-file [file]`: Output to the specified file, otherwise STDOUT
+- `-v`, `--validate`: Validate JSON5 but do not output JSON
+- `-V`, `--version`: Output the version number
+- `-h`, `--help`: Output usage information
+

+## Credits
+[Assem Kishore](https://github.com/aseemk) founded this project.
+
+[Michael Bolin](http://bolinfest.com/) independently arrived at and published
+some of these same ideas with awesome explanations and detail. Recommended
+reading: [Suggested Improvements to JSON](http://bolinfest.com/essays/json.html)
+
+[Douglas Crockford](http://www.crockford.com/) of course designed and built
+JSON, but his state machine diagrams on the [JSON website](http://json.org/), as
+cheesy as it may sound, gave us motivation and confidence that building a new
+parser to implement these ideas was within reach! The original
+implementation of JSON5 was also modeled directly off of Doug’s open-source
+[json_parse.js] parser. We’re grateful for that clean and well-documented
+code.

+// Load the full build.
+var _ = require('lodash');
+// Load the core build.
+var _ = require('lodash/core');
+// Load the FP build for immutable auto-curried iteratee-first data-last methods.
+var fp = require('lodash/fp');
+
+// Load method categories.
+var array = require('lodash/array');
+var object = require('lodash/fp/object');
+
+// Cherry-pick methods for smaller browserify/rollup/webpack bundles.
+var at = require('lodash/at');
+var curryN = require('lodash/fp/curryN');
+```
+
+See the [package source](https://github.com/lodash/lodash/tree/4.17.20-npm) for more details.
+
+**Note:**<br>

+   * Creates a `lodash` object which wraps `value` to enable implicit method

+   * and functions can be chained together. Methods that retrieve a single value
+   * or may return a primitive value will automatically end the chain sequence
+   * and return the unwrapped value. Otherwise, the value must be unwrapped
+   * with `_#value`.
+   *
+   * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+   * enabled using `_.chain`.
+   *
+   * The execution of chained methods is lazy, that is, it's deferred until
+   * `_#value` is implicitly or explicitly called.
+   *
+   * Lazy evaluation allows several methods to support shortcut fusion.
+   * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+   * the creation of intermediate arrays and can greatly reduce the number of
+   * iteratee executions. Sections of a chain sequence qualify for shortcut
+   * fusion if the section is applied to an array and iteratees accept only
+   * one argument. The heuristic for whether a section qualifies for shortcut
+   * fusion is subject to change.
+   *
+   * Chaining is supported in custom builds as long as the `_#value` method is
+   * directly or indirectly included in the build.
+   *
+   * In addition to lodash methods, wrappers have `Array` and `String` methods.
+   *

+   * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
+   *
+   * The wrapper `String` methods are:
+   * `replace` and `split`

+   * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
+   *

+     * Creates a `lodash` object which wraps `value` to enable implicit method
+     * chain sequences. Methods that operate on and return arrays, collections,
+     * and functions can be chained together. Methods that retrieve a single value
+     * or may return a primitive value will automatically end the chain sequence
+     * and return the unwrapped value. Otherwise, the value must be unwrapped
+     * with `_#value`.
+     *
+     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+     * enabled using `_.chain`.
+     *
+     * The execution of chained methods is lazy, that is, it's deferred until
+     * `_#value` is implicitly or explicitly called.
+     *
+     * Lazy evaluation allows several methods to support shortcut fusion.
+     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+     * the creation of intermediate arrays and can greatly reduce the number of
+     * iteratee executions. Sections of a chain sequence qualify for shortcut
+     * fusion if the section is applied to an array and iteratees accept only
+     * one argument. The heuristic for whether a section qualifies for shortcut
+     * fusion is subject to change.
+     *
+     * Chaining is supported in custom builds as long as the `_#value` method is
+     * directly or indirectly included in the build.
+     *
+     * In addition to lodash methods, wrappers have `Array` and `String` methods.
+     *
+     * The wrapper `Array` methods are:
+     * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
+     *
+     * The wrapper `String` methods are:
+     * `replace` and `split`
+     *
+     * The wrapper methods that support shortcut fusion are:
+     * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
+     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
+     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
+     *
+     * The chainable wrapper methods are:

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.log(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# security
+
+Previous versions had a prototype pollution bug that could cause privilege
+escalation in some circumstances when handling untrusted user input.
+
+Please use version 1.2.3 or later: https://snyk.io/vuln/SNYK-JS-MINIMIST-559764
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+
+  ```
+  > require('./')('one two three -- four five --six'.split(' '), { '--': true })
+  { _: [ 'one', 'two', 'three' ],
+    '--': [ 'four', 'five', '--six' ] }
+  ```
+
+  Note that with `opts['--']` set, parsing for arguments still stops after the
+  `--`.
+
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.
+
+# install
+
+With [npm](https://npmjs.org) do:
+
+```
+npm install minimist
+```

+# resolve
+
+implements the [node `require.resolve()`
+algorithm](https://nodejs.org/api/modules.html#modules_all_together)
+such that you can `require.resolve()` on behalf of a file asynchronously and
+synchronously
+
+[![build status](https://secure.travis-ci.org/browserify/resolve.png)](http://travis-ci.org/browserify/resolve)
+
+# example
+
+asynchronously resolve:
+
+```js
+var resolve = require('resolve');
+resolve('tap', { basedir: __dirname }, function (err, res) {
+    if (err) console.error(err);
+    else console.log(res);
+});
+```
+
+```
+$ node example/async.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+synchronously resolve:
+
+```js
+var resolve = require('resolve');
+var res = resolve.sync('tap', { basedir: __dirname });
+console.log(res);
+```
+
+```
+$ node example/sync.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+# methods
+
+```js
+var resolve = require('resolve');
+```
+
+For both the synchronous and asynchronous methods, errors may have any of the following `err.code` values:
+
+- `MODULE_NOT_FOUND`: the given path string (`id`) could not be resolved to a module
+- `INVALID_BASEDIR`: the specified `opts.basedir` doesn't exist, or is not a directory
+- `INVALID_PACKAGE_MAIN`: a `package.json` was encountered with an invalid `main` property (eg. not a string)
+
+## resolve(id, opts={}, cb)
+
+Asynchronously resolve the module path string `id` into `cb(err, res [, pkg])`, where `pkg` (if defined) is the data from `package.json`.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* opts.package - `package.json` data applicable to the module being loaded
+
+* opts.extensions - array of file extensions to search in order
+
+* opts.includeCoreModules - set to `false` to exclude node core modules (e.g. `fs`) from the search
+
+* opts.readFile - how to read files asynchronously
+
+* opts.isFile - function to asynchronously test whether a file exists
+
+* opts.isDirectory - function to asynchronously test whether a directory exists
+
+* opts.realpath - function to asynchronously resolve a potential symlink to its real path
+
+* `opts.packageFilter(pkg, pkgfile, dir)` - transform the parsed package.json contents before looking at the "main" field
+  * pkg - package data
+  * pkgfile - path to package.json
+  * dir - directory for package.json
+
+* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
+  * pkg - package data
+  * path - the path being resolved
+  * relativePath - the path relative from the package.json location
+  * returns - a relative path that will be joined from the package.json location
+
+* opts.paths - require.paths array to use if nothing is found on the normal `node_modules` recursive walk (probably don't use this)
+
+  For advanced users, `paths` can also be a `opts.paths(request, start, opts)` function
+    * request - the import specifier being resolved
+    * start - lookup path
+    * getNodeModulesDirs - a thunk (no-argument function) that returns the paths using standard `node_modules` resolution
+    * opts - the resolution options
+
+* `opts.packageIterator(request, start, opts)` - return the list of candidate paths where the packages sources may be found (probably don't use this)
+    * request - the import specifier being resolved
+    * start - lookup path
+    * getPackageCandidates - a thunk (no-argument function) that returns the paths using standard `node_modules` resolution
+    * opts - the resolution options
+
+* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`
+
+* opts.preserveSymlinks - if true, doesn't resolve `basedir` to real path before resolving.
+This is the way Node resolves dependencies when executed with the [--preserve-symlinks](https://nodejs.org/api/all.html#cli_preserve_symlinks) flag.
+**Note:** this property is currently `true` by default but it will be changed to
+`false` in the next major version because *Node's resolution algorithm does not preserve symlinks by default*.
+
+default `opts` values:
+
+```js
+{
+    paths: [],
+    basedir: __dirname,
+    extensions: ['.js'],
+    includeCoreModules: true,
+    readFile: fs.readFile,
+    isFile: function isFile(file, cb) {
+        fs.stat(file, function (err, stat) {
+            if (!err) {
+                return cb(null, stat.isFile() || stat.isFIFO());
+            }
+            if (err.code === 'ENOENT' || err.code === 'ENOTDIR') return cb(null, false);
+            return cb(err);
+        });

+
+## resolve.sync(id, opts)

+
+* `opts.packageFilter(pkg, dir)` - transform the parsed package.json contents before looking at the "main" field
+  * pkg - package data
+  * dir - directory for package.json (Note: the second argument will change to "pkgfile" in v2)
+
+* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
+  * pkg - package data
+  * path - the path being resolved
+  * relativePath - the path relative from the package.json location

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash
+npm install --save semver
+````
+
+## Usage
+
+As a node module:
+
+```js
+const semver = require('semver')
+
+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean('  =v1.2.3   ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+semver.minVersion('>=1.0.0') // '1.0.0'
+semver.valid(semver.coerce('v2')) // '2.0.0'
+semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
+```
+
+As a command-line utility:
+
+```
+$ semver -h
+
+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-p --include-prerelease
+        Always include prerelease versions in range matching
+
+-c --coerce
+        Coerce a string into SemVer if possible
+        (does not imply --loose)
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<https://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+Note that this behavior can be suppressed (treating all prerelease
+versions as if they were normal versions, for the purpose of range
+matching) by setting the `includePrerelease` flag on the options
+object to any
+[functions](https://github.com/npm/node-semver#functions) that do
+range matching.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero digit in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `options` object argument.  All
+options in this object are `false` by default.  The options supported
+are:
+
+- `loose`  Be more forgiving about not-quite-valid semver strings.
+  (Any resulting output will always be 100% strict compliant, of
+  course.)  For backwards compatibility reasons, if the `options`
+  argument is a boolean value instead of an object, it is interpreted
+  to be the `loose` param.
+- `includePrerelease`  Set to suppress the [default
+  behavior](https://github.com/npm/node-semver#prerelease-tags) of
+  excluding prerelease tagged versions from ranges unless they are
+  explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+* `parse(v)`: Attempt to parse a string as a semantic version, returning either
+  a `SemVer` object or `null`.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minVersion(range)`: Return the lowest version that can possibly match
+  the given range.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver string to
+semver. It looks for the first digit in a string, and consumes all
+remaining characters which satisfy at least a partial semver (e.g., `1`,
+`1.2`, `1.2.3`) up to the max permitted length (256 characters).  Longer
+versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).  All
+surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
+`3.4.0`).  Only text which lacks digits will fail coercion (`version one`
+is not valid).  The maximum  length for any semver component considered for
+coercion is 16 characters; longer components will be ignored
+(`10000000000000000.4.7.4` becomes `4.7.4`).  The maximum value for any
+semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
+components are invalid (`9999999999999999.4.7.4` is likely invalid).

+
+**@babel/eslint-parser** allows you to lint **ALL** valid Babel code with the fantastic
+[ESLint](https://github.com/eslint/eslint).
+
+## When should I use @babel/eslint-parser?
+
+ESLint's default parser and core rules [only support the latest final ECMAScript standard](https://github.com/eslint/eslint/blob/a675c89573836adaf108a932696b061946abf1e6/README.md#what-about-experimental-features) and do not support experimental (such as new features) and non-standard (such as Flow or TypeScript types) syntax provided by Babel. @babel/eslint-parser is a parser that allows ESLint to run on source code that is transformed by Babel.
+
+**Note:** You only need to use @babel/parser-eslint if you are using Babel to transform your code. If this is not the case, please use the relevant parser for your chosen flavor of ECMAScript (note that the default parser supports all non-experimental syntax as well as JSX).
+
+## How does it work?
+
+ESLint allows for the use of [custom parsers](https://eslint.org/docs/developer-guide/working-with-custom-parsers). When using this plugin, your code is parsed by Babel's parser (using the configuration specified in your [Babel configuration file](https://babeljs.io/docs/en/configuration)) and the resulting AST is
+transformed into an [ESTree](https://github.com/estree/estree)-compliant structure that ESLint can understand. All location info such as line numbers,
+columns is also retained so you can track down errors with ease.
+
+**Note:** ESLint's core rules do not support experimental syntax and may therefore not work as expected when using `@babel/eslint-parser`. Please use the companion [`@babel/eslint-plugin`](https://github.com/babel/babel/tree/main/eslint/babel-eslint-plugin) plugin for core rules that you have issues with.
+
+## Usage
+
+### Installation
+
+```sh
+$ npm install eslint @babel/core @babel/eslint-parser --save-dev
+# or
+$ yarn add eslint @babel/core @babel/eslint-parser -D
+```
+
+**Note:** @babel/eslint-parser requires `@babel/core@>=7.2.0` and a valid Babel configuration file to run. If you do not have this already set up, please see the [Babel Usage Guide](https://babeljs.io/docs/en/usage).
+
+### Setup
+
+To use @babel/eslint-parser, `"@babel/eslint-parser"` must be specified as the `parser` in your ESLint configuration file (see [here](https://eslint.org/docs/user-guide/configuring#specifying-parser) for more detailed information).
+
+**.eslintrc.js**
+
+```js
+module.exports = {
+  parser: "@babel/eslint-parser",
+};
+```
+
+With the parser set, your configuration can be configured as described in the [Configuring ESLint](https://eslint.org/docs/user-guide/configuring) documentation.
+
+**Note:** The `parserOptions` described in the [official documentation](https://eslint.org/docs/user-guide/configuring#specifying-parser-options) are for the default parser and are not necessarily supported by @babel/eslint-parser. Please see the section directly below for supported `parserOptions`.
+
+### Additional parser configuration
+
+Additional configuration options can be set in your ESLint configuration under the `parserOptions` key. Please note that the `ecmaFeatures` config property may still be required for ESLint to work properly with features not in ECMAScript 5 by default.
+
+- `requireConfigFile` (default `true`) can be set to `false` to allow @babel/eslint-parser to run on files that do not have a Babel configuration associated with them. This can be useful for linting files that are not transformed by Babel (such as tooling configuration files), though we recommend using the default parser via [glob-based configuration](https://eslint.org/docs/user-guide/configuring#configuration-based-on-glob-patterns). Note: @babel/eslint-parser will not parse any experimental syntax when no configuration file is found.
+- `sourceType` can be set to `"module"`(default) or `"script"` if your code isn't using ECMAScript modules.
+- `allowImportExportEverywhere` (default `false`) can be set to `true` to allow import and export declarations to appear anywhere a statement is allowed if your build environment supports that. Otherwise import and export declarations can only appear at a program's top level.
+- `ecmaFeatures.globalReturn` (default `false`) allow return statements in the global scope when used with `sourceType: "script"`.
+- `babelOptions` is an object containing Babel configuration [options](https://babeljs.io/docs/en/options) that are passed to Babel's parser at runtime. For cases where users might not want to use a Babel configuration file or are running Babel through another tool (such as Webpack with `babel-loader`).
+
+**.eslintrc.js**
+
+```js
+module.exports = {
+  parser: "@babel/eslint-parser",
+  parserOptions: {
+    sourceType: "module",
+    allowImportExportEverywhere: false,
+    ecmaFeatures: {
+      globalReturn: false,
+    },
+    babelOptions: {
+      configFile: "path/to/config.js",
+    },
+  },
+};
+```
+
+**.eslintrc.js using glob-based configuration**
+
+This configuration would use the default parser for all files except for those found by the `"files/transformed/by/babel/*.js"` glob.
+
+```js
+module.exports = {
+  rules: {
+    indent: "error",
+  },
+  overrides: [
+    {
+      files: ["files/transformed/by/babel/*.js"],
+      parser: "@babel/eslint-parser",
+    },
+  ],
+};
+```
+
+### Run
+
+```sh
+$ ./node_modules/.bin/eslint yourfile.js
+```

+> Check out [eslint-plugin-flowtype](https://github.com/gajus/eslint-plugin-flowtype): An `eslint` plugin that makes flow type annotations global variables and marks declarations as used. Solves the problem of false positives with `no-undef` and `no-unused-vars`.
+
+- `no-undef` for global flow types: `ReactElement`, `ReactClass` [#130](https://github.com/babel/@babel/eslint-parser/issues/130#issuecomment-111215076)
+  - Workaround: define types as globals in `.eslintrc` or define types and import them `import type ReactElement from './types'`
+- `no-unused-vars/no-undef` with Flow declarations (`declare module A {}`) [#132](https://github.com/babel/@babel/eslint-parser/issues/132#issuecomment-112815926)
+
+Modules/strict mode
+
+- `no-unused-vars: ["error", { vars: local }]` [#136](https://github.com/babel/@babel/eslint-parser/issues/136)
+
+Please check out [eslint-plugin-react](https://github.com/yannickcr/eslint-plugin-react) for React/JSX issues.
+
+- `no-unused-vars` with jsx
+
+Please check out [eslint-plugin-babel](https://github.com/babel/eslint-plugin-babel) for other issues.
+
+## Questions and support
+
+If you have an issue, please first check if it can be reproduced with the default parser and with the latest versions of `eslint` and `@babel/eslint-parser`. If it is not reproducible with the default parser, it is most likely an issue with `@babel/eslint-parser`.
+
+For questions and support please visit the [`#discussion`](https://babeljs.slack.com/messages/discussion/) Babel Slack channel (sign up [here](https://github.com/babel/notes/issues/38)) or the ESLint [Gitter](https://gitter.im/eslint/eslint).

+# ESLint Scope
+
+ESLint Scope is the [ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm) scope analyzer used in ESLint. It is a fork of [escope](http://github.com/estools/escope).
+
+## Usage
+
+Install:
+
+```
+npm i eslint-scope --save
+```
+
+Example:
+
+```js
+var eslintScope = require('eslint-scope');
+var espree = require('espree');
+var estraverse = require('estraverse');
+
+var ast = espree.parse(code);
+var scopeManager = eslintScope.analyze(ast);
+
+var currentScope = scopeManager.acquire(ast);   // global scope
+
+estraverse.traverse(ast, {
+    enter: function(node, parent) {
+        // do stuff
+
+        if (/Function/.test(node.type)) {
+            currentScope = scopeManager.acquire(node);  // get current function scope
+        }
+    },
+    leave: function(node, parent) {
+        if (/Function/.test(node.type)) {
+            currentScope = currentScope.upper;  // set to parent scope
+        }
+
+        // do stuff
+    }
+});
+```

+### Esrecurse [![Build Status](https://travis-ci.org/estools/esrecurse.svg?branch=master)](https://travis-ci.org/estools/esrecurse)
+
+Esrecurse ([esrecurse](https://github.com/estools/esrecurse)) is
+[ECMAScript](https://www.ecma-international.org/publications/standards/Ecma-262.htm)
+recursive traversing functionality.
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+esrecurse.visit(ast, {
+    XXXStatement: function (node) {
+        this.visit(node.left);
+        // do something...
+        this.visit(node.right);
+    }
+});
+```
+
+We can use `Visitor` instance.
+
+```javascript
+var visitor = new esrecurse.Visitor({
+    XXXStatement: function (node) {
+        this.visit(node.left);
+        // do something...
+        this.visit(node.right);
+    }
+});
+
+visitor.visit(ast);
+```
+
+We can inherit `Visitor` instance easily.
+
+```javascript
+class Derived extends esrecurse.Visitor {
+    constructor()
+    {
+        super(null);
+    }
+
+    XXXStatement(node) {
+    }
+}
+```
+
+```javascript
+function DerivedVisitor() {
+    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);
+}
+util.inherits(DerivedVisitor, esrecurse.Visitor);
+DerivedVisitor.prototype.XXXStatement = function (node) {
+    this.visit(node.left);
+    // do something...
+    this.visit(node.right);
+};
+```
+
+And you can invoke default visiting operation inside custom visit operation.
+
+```javascript
+function DerivedVisitor() {
+    esrecurse.Visitor.call(/* this for constructor */  this  /* visitor object automatically becomes this. */);
+}
+util.inherits(DerivedVisitor, esrecurse.Visitor);
+DerivedVisitor.prototype.XXXStatement = function (node) {
+    // do something...
+    this.visitChildren(node);
+};
+```
+
+The `childVisitorKeys` option does customize the behaviour of `this.visitChildren(node)`.
+We can use user-defined node types.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+esrecurse.visit(
+    ast,
+    {
+        Literal: function (node) {
+            // do something...
+        }
+    },
+    {
+        // Extending the existing traversing rules.
+        childVisitorKeys: {
+            // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
+            TestExpression: ['argument']
+        }
+    }
+);
+```
+
+We can use the `fallback` option as well.
+If the `fallback` option is `"iteration"`, `esrecurse` would visit all enumerable properties of unknown nodes.
+Please note circular references cause the stack overflow. AST might have circular references in additional properties for some purpose (e.g. `node.parent`).
+
+```javascript
+esrecurse.visit(
+    ast,
+    {
+        Literal: function (node) {
+            // do something...
+        }
+    },
+    {
+        fallback: 'iteration'
+    }
+);
+```
+
+If the `fallback` option is a function, `esrecurse` calls this function to determine the enumerable properties of unknown nodes.
+Please note circular references cause the stack overflow. AST might have circular references in additional properties for some purpose (e.g. `node.parent`).
+
+```javascript
+esrecurse.visit(
+    ast,
+    {
+        Literal: function (node) {
+            // do something...
+        }
+    },
+    {
+        fallback: function (node) {
+            return Object.keys(node).filter(function(key) {
+                return key !== 'argument'
+            });
+        }
+    }
+);
+```

+### Estraverse [![Build Status](https://secure.travis-ci.org/estools/estraverse.svg)](http://travis-ci.org/estools/estraverse)
+
+Estraverse ([estraverse](http://github.com/estools/estraverse)) is
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+traversal functions from [esmangle project](http://github.com/estools/esmangle).
+
+### Documentation
+
+You can find usage docs at [wiki page](https://github.com/estools/estraverse/wiki/Usage).
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node, parent) {
+        if (node.type == 'FunctionExpression' || node.type == 'FunctionDeclaration')
+            return estraverse.VisitorOption.Skip;
+    },
+    leave: function (node, parent) {
+        if (node.type == 'VariableDeclarator')
+          console.log(node.id.name);
+    }
+});
+```
+
+We can use `this.skip`, `this.remove` and `this.break` functions instead of using Skip, Remove and Break.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node) {
+        this.break();
+    }
+});
+```
+
+And estraverse provides `estraverse.replace` function. When returning node from `enter`/`leave`, current node is replaced with it.
+
+```javascript
+result = estraverse.replace(tree, {
+    enter: function (node) {
+        // Replace it with replaced.
+        if (node.type === 'Literal')
+            return replaced;
+    }
+});
+```
+
+By passing `visitor.keys` mapping, we can extend estraverse traversing functionality.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Extending the existing traversing rules.
+    keys: {
+        // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
+        TestExpression: ['argument']
+    }
+});
+```
+
+By passing `visitor.fallback` option, we can control the behavior when encountering unknown nodes.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Iterating the child **nodes** of unknown nodes.
+    fallback: 'iteration'
+});
+```
+
+When `visitor.fallback` is a function, we can determine which keys to visit on each node.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Skip the `argument` property of each node
+    fallback: function(node) {
+        return Object.keys(node).filter(function(key) {
+            return key !== 'argument';
+        });
+    }
+});
+```

+### Estraverse [![Build Status](https://secure.travis-ci.org/estools/estraverse.svg)](http://travis-ci.org/estools/estraverse)
+
+Estraverse ([estraverse](http://github.com/estools/estraverse)) is
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+traversal functions from [esmangle project](http://github.com/estools/esmangle).
+
+### Documentation
+
+You can find usage docs at [wiki page](https://github.com/estools/estraverse/wiki/Usage).
+
+### Example Usage
+
+The following code will output all variables declared at the root of a file.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node, parent) {
+        if (node.type == 'FunctionExpression' || node.type == 'FunctionDeclaration')
+            return estraverse.VisitorOption.Skip;
+    },
+    leave: function (node, parent) {
+        if (node.type == 'VariableDeclarator')
+          console.log(node.id.name);
+    }
+});
+```
+
+We can use `this.skip`, `this.remove` and `this.break` functions instead of using Skip, Remove and Break.
+
+```javascript
+estraverse.traverse(ast, {
+    enter: function (node) {
+        this.break();
+    }
+});
+```
+
+And estraverse provides `estraverse.replace` function. When returning node from `enter`/`leave`, current node is replaced with it.
+
+```javascript
+result = estraverse.replace(tree, {
+    enter: function (node) {
+        // Replace it with replaced.
+        if (node.type === 'Literal')
+            return replaced;
+    }
+});
+```
+
+By passing `visitor.keys` mapping, we can extend estraverse traversing functionality.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Extending the existing traversing rules.
+    keys: {
+        // TargetNodeName: [ 'keys', 'containing', 'the', 'other', '**node**' ]
+        TestExpression: ['argument']
+    }
+});
+```
+
+By passing `visitor.fallback` option, we can control the behavior when encountering unknown nodes.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Iterating the child **nodes** of unknown nodes.
+    fallback: 'iteration'
+});
+```
+
+When `visitor.fallback` is a function, we can determine which keys to visit on each node.
+
+```javascript
+// This tree contains a user-defined `TestExpression` node.
+var tree = {
+    type: 'TestExpression',
+
+    // This 'argument' is the property containing the other **node**.
+    argument: {
+        type: 'Literal',
+        value: 20
+    },
+
+    // This 'extended' is the property not containing the other **node**.
+    extended: true
+};
+estraverse.traverse(tree, {
+    enter: function (node) { },
+
+    // Skip the `argument` property of each node
+    fallback: function(node) {
+        return Object.keys(node).filter(function(key) {
+            return key !== 'argument';
+        });
+    }
+});
+```

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash
+npm install semver
+````
+
+## Usage
+
+As a node module:
+
+```js
+const semver = require('semver')
+
+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean('  =v1.2.3   ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+semver.minVersion('>=1.0.0') // '1.0.0'
+semver.valid(semver.coerce('v2')) // '2.0.0'
+semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
+```
+
+As a command-line utility:
+
+```
+$ semver -h
+
+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-p --include-prerelease
+        Always include prerelease versions in range matching
+
+-c --coerce
+        Coerce a string into SemVer if possible
+        (does not imply --loose)
+
+--rtl
+        Coerce version strings right to left
+
+--ltr
+        Coerce version strings left to right (default)
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<https://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+Note that this behavior can be suppressed (treating all prerelease
+versions as if they were normal versions, for the purpose of range
+matching) by setting the `includePrerelease` flag on the options
+object to any
+[functions](https://github.com/npm/node-semver#functions) that do
+range matching.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero element in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `options` object argument.  All
+options in this object are `false` by default.  The options supported
+are:
+
+- `loose`  Be more forgiving about not-quite-valid semver strings.
+  (Any resulting output will always be 100% strict compliant, of
+  course.)  For backwards compatibility reasons, if the `options`
+  argument is a boolean value instead of an object, it is interpreted
+  to be the `loose` param.
+- `includePrerelease`  Set to suppress the [default
+  behavior](https://github.com/npm/node-semver#prerelease-tags) of
+  excluding prerelease tagged versions from ranges unless they are
+  explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+* `parse(v)`: Attempt to parse a string as a semantic version, returning either
+  a `SemVer` object or `null`.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
+  are equal.  Sorts in ascending order if passed to `Array.sort()`.
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minVersion(range)`: Return the lowest version that can possibly match
+  the given range.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version, options)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver string to
+semver. It looks for the first digit in a string, and consumes all
+remaining characters which satisfy at least a partial semver (e.g., `1`,
+`1.2`, `1.2.3`) up to the max permitted length (256 characters).  Longer
+versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).  All
+surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
+`3.4.0`).  Only text which lacks digits will fail coercion (`version one`
+is not valid).  The maximum  length for any semver component considered for
+coercion is 16 characters; longer components will be ignored
+(`10000000000000000.4.7.4` becomes `4.7.4`).  The maximum value for any
+semver component is `Integer.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
+components are invalid (`9999999999999999.4.7.4` is likely invalid).
+
+If the `options.rtl` flag is set, then `coerce` will return the right-most
+coercible tuple that does not share an ending index with a longer coercible
+tuple.  For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
+`4.0.0`.  `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
+any other overlapping SemVer tuple.
+
+### Clean
+
+* `clean(version)`: Clean a string to be a valid semver if possible
+
+This will return a cleaned and trimmed semver version. If the provided version is not valid a null will be returned. This does not work for ranges. 
+
+ex.
+* `s.clean(' = v 2.1.5foo')`: `null`
+* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean(' = v 2.1.5-foo')`: `null`
+* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean('=v2.1.5')`: `'2.1.5'`
+* `s.clean('  =v2.1.5')`: `2.1.5`
+* `s.clean('      2.1.5   ')`: `'2.1.5'`
+* `s.clean('~1.0.0')`: `null`

-# babel-eslint [![npm](https://img.shields.io/npm/v/babel-eslint.svg)](https://www.npmjs.com/package/babel-eslint) [![travis](https://img.shields.io/travis/babel/babel-eslint/master.svg)](https://travis-ci.org/babel/babel-eslint) [![npm-downloads](https://img.shields.io/npm/dm/babel-eslint.svg)](https://www.npmjs.com/package/babel-eslint)
-
-**babel-eslint** allows you to lint **ALL** valid Babel code with the fantastic
-[ESLint](https://github.com/eslint/eslint).
-
-### Why Use babel-eslint
-
-You only need to use babel-eslint if you are using types (Flow) or experimental features not supported in ESLint itself yet. Otherwise try the default parser (you don't have to use it just because you are using Babel).
-
----
-
-> If there is an issue, first check if it can be reproduced with the regular parser or with the latest versions of `eslint` and `babel-eslint`!
-
-For questions and support please visit the [`#discussion`](https://babeljs.slack.com/messages/discussion/) babel slack channel (sign up [here](https://github.com/babel/notes/issues/38)) or eslint [gitter](https://gitter.im/eslint/eslint)!
-
-> Note that the `ecmaFeatures` config property may still be required for ESLint to work properly with features not in ECMAScript 5 by default. Examples are `globalReturn` and `modules`).
-
-## Known Issues
-
-Flow:
-> Check out [eslint-plugin-flowtype](https://github.com/gajus/eslint-plugin-flowtype): An `eslint` plugin that makes flow type annotations global variables and marks declarations as used. Solves the problem of false positives with `no-undef` and `no-unused-vars`.
-- `no-undef` for global flow types: `ReactElement`, `ReactClass` [#130](https://github.com/babel/babel-eslint/issues/130#issuecomment-111215076)
-  - Workaround: define types as globals in `.eslintrc` or define types and import them `import type ReactElement from './types'`
-- `no-unused-vars/no-undef` with Flow declarations (`declare module A {}`) [#132](https://github.com/babel/babel-eslint/issues/132#issuecomment-112815926)
-
-Modules/strict mode
-- `no-unused-vars: [2, {vars: local}]` [#136](https://github.com/babel/babel-eslint/issues/136)
-
-Please check out [eslint-plugin-react](https://github.com/yannickcr/eslint-plugin-react) for React/JSX issues
-- `no-unused-vars` with jsx
-
-Please check out [eslint-plugin-babel](https://github.com/babel/eslint-plugin-babel) for other issues
-
-## How does it work?
-
-ESLint allows custom parsers. This is great but some of the syntax nodes that Babel supports
-aren't supported by ESLint. When using this plugin, ESLint is monkeypatched and your code is
-transformed into code that ESLint can understand. All location info such as line numbers,
-columns is also retained so you can track down errors with ease.
-
-Basically `babel-eslint` exports an [`index.js`](/index.js) that a linter can use.
-It just needs to export a `parse` method that takes in a string of code and outputs an AST.
-
-## Usage
-
-### Supported ESLint versions
-
-ESLint | babel-eslint
------------- | -------------
-4.x | >= 6.x
-3.x | >= 6.x
-2.x | >= 6.x
-1.x | >= 5.x
-
-### Install
-
-Ensure that you have substituted the correct version lock for `eslint` and `babel-eslint` into this command:
-
-```sh
-$ npm install eslint@4.x babel-eslint@8 --save-dev
-# or
-$ yarn add eslint@4.x babel-eslint@8 -D
-```
-
-### Setup
-
-**.eslintrc**
-
-```json
-{
-  "parser": "babel-eslint",
-  "rules": {
-    "strict": 0
-  }
-}
-```
-
-Check out the [ESLint docs](http://eslint.org/docs/rules/) for all possible rules.
-
-### Configuration
-
-- `sourceType` can be set to `'module'`(default) or `'script'` if your code isn't using ECMAScript modules.
-- `allowImportExportEverywhere` (default `false`) can be set to `true` to allow import and export declarations to appear anywhere a statement is allowed if your build environment supports that. Otherwise import and export declarations can only appear at a program's top level.
-- `codeFrame` (default `true`) can be set to `false` to disable the code frame in the reporter. This is useful since some eslint formatters don't play well with it.
-
-**.eslintrc**
-
-```json
-{
-  "parser": "babel-eslint",
-  "parserOptions": {
-    "sourceType": "module",
-    "allowImportExportEverywhere": false,
-    "codeFrame": true
-  }
-}
-```
-
-### Run
-
-```sh
-$ eslint your-files-here
-```

-### esutils [![Build Status](https://secure.travis-ci.org/estools/esutils.svg)](http://travis-ci.org/estools/esutils)
-esutils ([esutils](http://github.com/estools/esutils)) is
-utility box for ECMAScript language tools.
-
-### API
-
-### ast
-
-#### ast.isExpression(node)
-
-Returns true if `node` is an Expression as defined in ECMA262 edition 5.1 section
-[11](https://es5.github.io/#x11).
-
-#### ast.isStatement(node)
-
-Returns true if `node` is a Statement as defined in ECMA262 edition 5.1 section
-[12](https://es5.github.io/#x12).
-
-#### ast.isIterationStatement(node)
-
-Returns true if `node` is an IterationStatement as defined in ECMA262 edition
-5.1 section [12.6](https://es5.github.io/#x12.6).
-
-#### ast.isSourceElement(node)
-
-Returns true if `node` is a SourceElement as defined in ECMA262 edition 5.1
-section [14](https://es5.github.io/#x14).
-
-#### ast.trailingStatement(node)
-
-Returns `Statement?` if `node` has trailing `Statement`.
-```js
-if (cond)
-    consequent;
-```
-When taking this `IfStatement`, returns `consequent;` statement.
-
-#### ast.isProblematicIfStatement(node)
-
-Returns true if `node` is a problematic IfStatement. If `node` is a problematic `IfStatement`, `node` cannot be represented as an one on one JavaScript code.
-```js
-{
-    type: 'IfStatement',
-    consequent: {
-        type: 'WithStatement',
-        body: {
-            type: 'IfStatement',
-            consequent: {type: 'EmptyStatement'}
-        }
-    },
-    alternate: {type: 'EmptyStatement'}
-}
-```
-The above node cannot be represented as a JavaScript code, since the top level `else` alternate belongs to an inner `IfStatement`.
-
-
-### code
-
-#### code.isDecimalDigit(code)
-
-Return true if provided code is decimal digit.
-
-#### code.isHexDigit(code)
-
-Return true if provided code is hexadecimal digit.
-
-#### code.isOctalDigit(code)
-
-Return true if provided code is octal digit.
-
-#### code.isWhiteSpace(code)
-
-Return true if provided code is white space. White space characters are formally defined in ECMA262.
-
-#### code.isLineTerminator(code)
-
-Return true if provided code is line terminator. Line terminator characters are formally defined in ECMA262.
-
-#### code.isIdentifierStart(code)
-
-Return true if provided code can be the first character of ECMA262 Identifier. They are formally defined in ECMA262.
-
-#### code.isIdentifierPart(code)
-
-Return true if provided code can be the trailing character of ECMA262 Identifier. They are formally defined in ECMA262.
-
-### keyword
-
-#### keyword.isKeywordES5(id, strict)
-
-Returns `true` if provided identifier string is a Keyword or Future Reserved Word
-in ECMA262 edition 5.1. They are formally defined in ECMA262 sections
-[7.6.1.1](http://es5.github.io/#x7.6.1.1) and [7.6.1.2](http://es5.github.io/#x7.6.1.2),
-respectively. If the `strict` flag is truthy, this function additionally checks whether
-`id` is a Keyword or Future Reserved Word under strict mode.
-
-#### keyword.isKeywordES6(id, strict)
-
-Returns `true` if provided identifier string is a Keyword or Future Reserved Word
-in ECMA262 edition 6. They are formally defined in ECMA262 sections
-[11.6.2.1](http://ecma-international.org/ecma-262/6.0/#sec-keywords) and
-[11.6.2.2](http://ecma-international.org/ecma-262/6.0/#sec-future-reserved-words),
-respectively. If the `strict` flag is truthy, this function additionally checks whether
-`id` is a Keyword or Future Reserved Word under strict mode.
-
-#### keyword.isReservedWordES5(id, strict)
-
-Returns `true` if provided identifier string is a Reserved Word in ECMA262 edition 5.1.
-They are formally defined in ECMA262 section [7.6.1](http://es5.github.io/#x7.6.1).
-If the `strict` flag is truthy, this function additionally checks whether `id`
-is a Reserved Word under strict mode.
-
-#### keyword.isReservedWordES6(id, strict)
-
-Returns `true` if provided identifier string is a Reserved Word in ECMA262 edition 6.
-They are formally defined in ECMA262 section [11.6.2](http://ecma-international.org/ecma-262/6.0/#sec-reserved-words).
-If the `strict` flag is truthy, this function additionally checks whether `id`
-is a Reserved Word under strict mode.
-
-#### keyword.isRestrictedWord(id)
-
-Returns `true` if provided identifier string is one of `eval` or `arguments`.
-They are restricted in strict mode code throughout ECMA262 edition 5.1 and
-in ECMA262 edition 6 section [12.1.1](http://ecma-international.org/ecma-262/6.0/#sec-identifiers-static-semantics-early-errors).
-
-#### keyword.isIdentifierNameES5(id)
-
-Return true if provided identifier string is an IdentifierName as specified in
-ECMA262 edition 5.1 section [7.6](https://es5.github.io/#x7.6).

-   * Creates a `lodash` object which wraps `value` to enable implicit method
-   * chain sequences. Methods that operate on and return arrays, collections,
-   * and functions can be chained together. Methods that retrieve a single value
-   * or may return a primitive value will automatically end the chain sequence
-   * and return the unwrapped value. Otherwise, the value must be unwrapped
-   * with `_#value`.
-   *
-   * Explicit chain sequences, which must be unwrapped with `_#value`, may be

-   *
-   * The execution of chained methods is lazy, that is, it's deferred until
-   * `_#value` is implicitly or explicitly called.
-   *
-   * Lazy evaluation allows several methods to support shortcut fusion.
-   * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-   * the creation of intermediate arrays and can greatly reduce the number of
-   * iteratee executions. Sections of a chain sequence qualify for shortcut
-   * fusion if the section is applied to an array and iteratees accept only
-   * one argument. The heuristic for whether a section qualifies for shortcut
-   * fusion is subject to change.
-   *
-   * Chaining is supported in custom builds as long as the `_#value` method is
-   * directly or indirectly included in the build.
-   *
-   * In addition to lodash methods, wrappers have `Array` and `String` methods.
-   *
-   * The wrapper `Array` methods are:

-   *
-   * The wrapper `String` methods are:

-   * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
-   *

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. Methods that operate on and return arrays, collections,
-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.
-     *
-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array and iteratees accept only
-     * one argument. The heuristic for whether a section qualifies for shortcut
-     * fusion is subject to change.
-     *
-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.
-     *

-     *
-     * The wrapper `String` methods are:

-# resolve
-
-implements the [node `require.resolve()`
-algorithm](https://nodejs.org/api/modules.html#modules_all_together)
-such that you can `require.resolve()` on behalf of a file asynchronously and
-synchronously
-
-[![build status](https://secure.travis-ci.org/browserify/node-resolve.png)](http://travis-ci.org/browserify/node-resolve)
-
-# example
-
-asynchronously resolve:
-
-```js
-var resolve = require('resolve');
-resolve('tap', { basedir: __dirname }, function (err, res) {
-    if (err) console.error(err);
-    else console.log(res);
-});
-```
-
-```
-$ node example/async.js
-/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
-```
-
-synchronously resolve:
-
-```js
-var resolve = require('resolve');
-var res = resolve.sync('tap', { basedir: __dirname });
-console.log(res);
-```
-
-```
-$ node example/sync.js
-/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
-```
-
-# methods
-
-```js
-var resolve = require('resolve');
-```
-
-## resolve(id, opts={}, cb)
-
-Asynchronously resolve the module path string `id` into `cb(err, res [, pkg])`, where `pkg` (if defined) is the data from `package.json`.
-
-options are:
-
-* opts.basedir - directory to begin resolving from
-
-* opts.package - `package.json` data applicable to the module being loaded
-
-* opts.extensions - array of file extensions to search in order
-
-* opts.readFile - how to read files asynchronously
-
-* opts.isFile - function to asynchronously test whether a file exists
-
-* opts.isDirectory - function to asynchronously test whether a directory exists
-
-* `opts.packageFilter(pkg, pkgfile)` - transform the parsed package.json contents before looking at the "main" field
-  * pkg - package data
-  * pkgfile - path to package.json
-
-* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
-  * pkg - package data
-  * path - the path being resolved
-  * relativePath - the path relative from the package.json location
-  * returns - a relative path that will be joined from the package.json location
-
-* opts.paths - require.paths array to use if nothing is found on the normal `node_modules` recursive walk (probably don't use this)
-
-  For advanced users, `paths` can also be a `opts.paths(request, start, opts)` function
-    * request - the import specifier being resolved
-    * start - lookup path
-    * getNodeModulesDirs - a thunk (no-argument function) that returns the paths using standard `node_modules` resolution
-    * opts - the resolution options
-
-* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`
-
-* opts.preserveSymlinks - if true, doesn't resolve `basedir` to real path before resolving.
-This is the way Node resolves dependencies when executed with the [--preserve-symlinks](https://nodejs.org/api/all.html#cli_preserve_symlinks) flag.
-**Note:** this property is currently `true` by default but it will be changed to
-`false` in the next major version because *Node's resolution algorithm does not preserve symlinks by default*.
-
-default `opts` values:
-
-```js
-{
-    paths: [],
-    basedir: __dirname,
-    extensions: ['.js'],
-    readFile: fs.readFile,
-    isFile: function isFile(file, cb) {
-        fs.stat(file, function (err, stat) {
-            if (!err) {
-                return cb(null, stat.isFile() || stat.isFIFO());
-            }
-            if (err.code === 'ENOENT' || err.code === 'ENOTDIR') return cb(null, false);
-            return cb(err);
-        });

-
-## resolve.sync(id, opts)
-
-Synchronously resolve the module path string `id`, returning the result and
-throwing an error when `id` can't be resolved.

-
-* opts.extensions - array of file extensions to search in order
-
-* opts.readFile - how to read files synchronously
-
-* opts.isFile - function to synchronously test whether a file exists
-
-* opts.isDirectory - function to synchronously test whether a directory exists
-
-* `opts.packageFilter(pkg, dir)` - transform the parsed package.json contents before looking at the "main" field
-  * pkg - package data
-  * dir - directory for package.json (Note: the second argument will change to "pkgfile" in v2)
-
-* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
-  * pkg - package data
-  * path - the path being resolved
-  * relativePath - the path relative from the package.json location
-  * returns - a relative path that will be joined from the package.json location
-
-* opts.paths - require.paths array to use if nothing is found on the normal `node_modules` recursive walk (probably don't use this)
