npmlog@2.0.0

Override default EventEmitter error-handling behavior. Some people might want
to log messages with 'error' as the name. Only semver-major because there might
have been somebody relying on the fact that npmlog was an EE.

+# npmlog
+
+The logger util that npm uses.
+
+This logger is very basic.  It does the logging for npm.  It supports
+custom levels and colored output.
+
+By default, logs are written to stderr.  If you want to send log messages
+to outputs other than streams, then you can change the `log.stream`
+member, or you can just listen to the events that it emits, and do
+whatever you want with them.
+
+# Basic Usage
+
+```
+var log = require('npmlog')
+
+// additional stuff ---------------------------+
+// message ----------+                         |
+// prefix ----+      |                         |
+// level -+   |      |                         |
+//        v   v      v                         v
+    log.info('fyi', 'I have a kitty cat: %j', myKittyCat)
+```
+
+## log.level
+
+* {String}
+
+The level to display logs at.  Any logs at or above this level will be
+displayed.  The special level `silent` will prevent anything from being
+displayed ever.
+
+## log.record
+
+* {Array}
+
+An array of all the log messages that have been entered.
+
+## log.maxRecordSize
+
+* {Number}
+
+The maximum number of records to keep.  If log.record gets bigger than
+10% over this value, then it is sliced down to 90% of this value.
+
+The reason for the 10% window is so that it doesn't have to resize a
+large array on every log entry.
+
+## log.prefixStyle
+
+* {Object}
+
+A style object that specifies how prefixes are styled.  (See below)
+
+## log.headingStyle
+
+* {Object}
+
+A style object that specifies how the heading is styled.  (See below)
+
+## log.heading
+
+* {String} Default: ""
+
+If set, a heading that is printed at the start of every line.
+
+## log.stream
+
+* {Stream} Default: `process.stderr`
+
+The stream where output is written.
+
+## log.enableColor()
+
+Force colors to be used on all messages, regardless of the output
+stream.
+
+## log.disableColor()
+
+Disable colors on all messages.
+
+## log.enableProgress()
+
+Enable the display of log activity spinner and progress bar
+
+## log.disableProgress()
+
+Disable the display of a progress bar
+
+## log.enableUnicode()
+
+Force the unicode theme to be used for the progress bar.
+
+## log.disableUnicode()
+
+Disable the use of unicode in the progress bar.
+
+## log.setGaugeTemplate(template)
+
+Overrides the default gauge template.
+
+## log.pause()
+
+Stop emitting messages to the stream, but do not drop them.
+
+## log.resume()
+
+Emit all buffered messages that were written while paused.
+
+## log.log(level, prefix, message, ...)
+
+* `level` {String} The level to emit the message at
+* `prefix` {String} A string prefix.  Set to "" to skip.
+* `message...` Arguments to `util.format`
+
+Emit a log message at the specified level.
+
+## log\[level](prefix, message, ...)
+
+For example,
+
+* log.silly(prefix, message, ...)
+* log.verbose(prefix, message, ...)
+* log.info(prefix, message, ...)
+* log.http(prefix, message, ...)
+* log.warn(prefix, message, ...)
+* log.error(prefix, message, ...)
+
+Like `log.log(level, prefix, message, ...)`.  In this way, each level is
+given a shorthand, so you can do `log.info(prefix, message)`.
+
+## log.addLevel(level, n, style, disp)
+
+* `level` {String} Level indicator
+* `n` {Number} The numeric level
+* `style` {Object} Object with fg, bg, inverse, etc.
+* `disp` {String} Optional replacement for `level` in the output.
+
+Sets up a new level with a shorthand function and so forth.
+
+Note that if the number is `Infinity`, then setting the level to that
+will cause all log messages to be suppressed.  If the number is
+`-Infinity`, then the only way to show it is to enable all log messages.
+
+## log.newItem(name, todo, weight)
+
+* `name` {String} Optional; progress item name.
+* `todo` {Number} Optional; total amount of work to be done. Default 0.
+* `weight` {Number} Optional; the weight of this item relative to others. Default 1.
+
+This adds a new `are-we-there-yet` item tracker to the progress tracker. The
+object returned has the `log[level]` methods but is otherwise an
+`are-we-there-yet` `Tracker` object.
+
+## log.newStream(name, todo, weight)
+
+This adds a new `are-we-there-yet` stream tracker to the progress tracker. The
+object returned has the `log[level]` methods but is otherwise an
+`are-we-there-yet` `TrackerStream` object.
+
+## log.newGroup(name, weight)
+
+This adds a new `are-we-there-yet` tracker group to the progress tracker. The
+object returned has the `log[level]` methods but is otherwise an
+`are-we-there-yet` `TrackerGroup` object.
+
+# Events
+
+Events are all emitted with the message object.
+
+* `log` Emitted for all messages
+* `log.<level>` Emitted for all messages with the `<level>` level.
+* `<prefix>` Messages with prefixes also emit their prefix as an event.
+
+# Style Objects
+
+Style objects can have the following fields:
+
+* `fg` {String} Color for the foreground text
+* `bg` {String} Color for the background
+* `bold`, `inverse`, `underline` {Boolean} Set the associated property
+* `bell` {Boolean} Make a noise (This is pretty annoying, probably.)
+
+# Message Objects
+
+Every log event is emitted with a message object, and the `log.record`
+list contains all of them that have been created.  They have the
+following fields:
+
+* `id` {Number}
+* `level` {String}
+* `prefix` {String}
+* `message` {String} Result of `util.format()`
+* `messageRaw` {Array} Arguments to `util.format()`

+ansi.js
+=========
+### Advanced ANSI formatting tool for Node.js
+
+`ansi.js` is a module for Node.js that provides an easy-to-use API for
+writing ANSI escape codes to `Stream` instances. ANSI escape codes are used to do
+fancy things in a terminal window, like render text in colors, delete characters,
+lines, the entire window, or hide and show the cursor, and lots more!
+
+#### Features:
+
+ * 256 color support for the terminal!
+ * Make a beep sound from your terminal!
+ * Works with *any* writable `Stream` instance.
+ * Allows you to move the cursor anywhere on the terminal window.
+ * Allows you to delete existing contents from the terminal window.
+ * Allows you to hide and show the cursor.
+ * Converts CSS color codes and RGB values into ANSI escape codes.
+ * Low-level; you are in control of when escape codes are used, it's not abstracted.
+
+
+Installation
+------------
+
+Install with `npm`:
+
+``` bash
+$ npm install ansi
+```
+
+
+Example
+-------
+
+``` js
+var ansi = require('ansi')
+  , cursor = ansi(process.stdout)
+
+// You can chain your calls forever:
+cursor
+  .red()                 // Set font color to red
+  .bg.grey()             // Set background color to grey
+  .write('Hello World!') // Write 'Hello World!' to stdout
+  .bg.reset()            // Reset the bgcolor before writing the trailing \n,
+                         //      to avoid Terminal glitches
+  .write('\n')           // And a final \n to wrap things up
+
+// Rendering modes are persistent:
+cursor.hex('#660000').bold().underline()
+
+// You can use the regular logging functions, text will be green:
+console.log('This is blood red, bold text')
+
+// To reset just the foreground color:
+cursor.fg.reset()
+
+console.log('This will still be bold')
+
+// to go to a location (x,y) on the console
+// note: 1-indexed, not 0-indexed:
+cursor.goto(10, 5).write('Five down, ten over')
+
+// to clear the current line:
+cursor.horizontalAbsolute(0).eraseLine().write('Starting again')
+
+// to go to a different column on the current line:
+cursor.horizontalAbsolute(5).write('column five')
+
+// Clean up after yourself!
+cursor.reset()

+recursive fan-out and gather type workflows that are so common in async.
+
+What you do with this completion data is up to you, but the most common use case is to
+feed it to one of the many progress bar modules.
+
+Most progress bar modules include a rudamentary version of this, but my
+needs were more complex.
+
+Usage
+=====
+
+```javascript
+var TrackerGroup = require("are-we-there-yet").TrackerGroup
+
+var top = new TrackerGroup("program")
+
+var single = top.newItem("one thing", 100)
+single.completeWork(20)
+
+console.log(top.completed()) // 0.2
+
+fs.stat("file", function(er, stat) {
+  if (er) throw er  
+  var stream = top.newStream("file", stat.size)
+  console.log(top.completed()) // now 0.1 as single is 50% of the job and is 20% complete
+                              // and 50% * 20% == 10%
+  fs.createReadStream("file").pipe(stream).on("data", function (chunk) {
+    // do stuff with chunk
+  })
+  top.on("change", function (name) {
+    // called each time a chunk is read from "file"
+    // top.completed() will start at 0.1 and fill up to 0.6 as the file is read
+  })
+})
+```
+
+Shared Methods
+==============
+
+All tracker objects described below have the following methods, they, along
+with the event comprise the interface for consumers of tracker objects.
+
+* var completed = tracker.completed()
+
+Returns the ratio of completed work to work to be done. Range of 0 to 1.
+
+* tracker.finish()
+
+Marks the tracker as completed. With a TrackerGroup this marks all of its
+components as completed.
+
+Marks all of the components of this tracker as finished, which in turn means
+that `tracker.completed()` for this will now be 1.
+
+This will result in one or more `change` events being emitted.
+
+Events
+======
+
+All tracker objects emit `change` events with an argument of the name of the
+thing changing.
+
+TrackerGroup
+============
+
+* var tracker = new TrackerGroup(**name**)
+
+  * **name** *(optional)* - The name of this tracker group, used in change
+    notifications if the component updating didn't have a name. Defaults to undefined.
+
+Creates a new empty tracker aggregation group. These are trackers whose
+completion status is determined by the completion status of other trackers.
+
+* tracker.addUnit(**otherTracker**, **weight**)
+
+  * **otherTracker** - Any of the other are-we-there-yet tracker objects
+  * **weight** *(optional)* - The weight to give the tracker, defaults to 1.
+
+Adds the **otherTracker** to this aggregation group. The weight determines
+how long you expect this tracker to take to complete in proportion to other
+units.  So for instance, if you add one tracker with a weight of 1 and
+another with a weight of 2, you're saying the second will take twice as long
+to complete as the first.  As such, the first will account for 33% of the
+completion of this tracker and the second will account for the other 67%.
+
+Returns **otherTracker**.
+
+* var subGroup = tracker.newGroup(**name**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subGroup = tracker.addUnit(new TrackerGroup(name), weight)
+```
+
+* var subItem = tracker.newItem(**name**, **todo**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subItem = tracker.addUnit(new Tracker(name, todo), weight)
+```
+
+* var subStream = tracker.newStream(**name**, **todo**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+  var subStream = tracker.addUnit(new TrackerStream(name, todo), weight)
+```
+
+* console.log( tracker.debug() )
+
+Returns a tree showing the completion of this tracker group and all of its
+children, including recursively entering all of the children.
+
+Tracker
+=======
+
+* var tracker = new Tracker(**name**, **todo**)
+
+  * **name** *(optional)* The name of this counter to report in change
+    events.  Defaults to undefined.
+  * **todo** *(optional)* The amount of work todo (a number). Defaults to 0.
+
+Ordinarily these are constructed as a part of a tracker group (via `newItem`) but they c
+
+* var completed = tracker.completed()
+
+Returns the ratio of completed work to work to be done. Range of 0 to 1. If
+total work to be done is 0 then it will return 0.
+
+* tracker.addWork(**todo**)
+
+  * **todo** A number to add to the amount of work to be done.
+
+Increases the amount of work to be done, thus decreasing the completion
+percentage.  Triggers a `change` event.
+
+* tracker.completeWork(**completed**)
+
+  * **completed** A number to add to the work complete
+
+Increase the amount of work complete, thus increasing the completion percentage.
+Will never increase the work completed past the amount of work todo. That is,
+percentages > 100% are not allowed. Triggers a `change` event.
+
+* tracker.finish()
+
+Marks this tracker as finished, tracker.completed() will now be 1. Triggers
+a `change` event.
+
+TrackerStream
+=============
+
+* var tracker = new TrackerStream(**name**, **size**, **options**)
+
+  * **name** *(optional)* The name of this counter to report in change
+    events.  Defaults to undefined.
+  * **size** *(optional)* The number of bytes being sent through this stream.
+  * **options** *(optional)* A hash of stream options
+
+The tracker stream object is a pass through stream that updates an internal
+tracker object each time a block passes through.  It's intended to track
+downloads, file extraction and other related activities. You use it by piping
+your data source into it and then using it as your data source.
+
+If your data has a length attribute then that's used as the amount of work
+completed when the chunk is passed through.  If it does not (eg, object
+streams) then each chunk counts as completing 1 unit of work, so your size
+should be the total number of objects being streamed.
+
+* tracker.addWork(**todo**)
+
+  * **todo** Increase the expected overall size by **todo** bytes.
+
+Increases the amount of work to be done, thus decreasing the completion
+percentage.  Triggers a `change` event.

+# delegates
+
+  Node method and accessor delegation utilty.
+
+## Installation
+
+```
+$ npm install delegates
+```
+
+## Example
+
+```js
+var delegate = require('delegates');
+
+...
+
+delegate(proto, 'request')
+  .method('acceptsLanguages')
+  .method('acceptsEncodings')
+  .method('acceptsCharsets')
+  .method('accepts')
+  .method('is')
+  .access('querystring')
+  .access('idempotent')
+  .access('socket')
+  .access('length')
+  .access('query')
+  .access('search')
+  .access('status')
+  .access('method')
+  .access('path')
+  .access('body')
+  .access('host')
+  .access('url')
+  .getter('subdomains')
+  .getter('protocol')
+  .getter('header')
+  .getter('stale')
+  .getter('fresh')
+  .getter('secure')
+  .getter('ips')
+  .getter('ip')
+```
+
+# API
+
+## Delegate(proto, prop)
+
+Creates a delegator instance used to configure using the `prop` on the given
+`proto` object. (which is usually a prototype)
+
+## Delegate#method(name)
+
+Allows the given method `name` to be accessed on the host.
+
+## Delegate#getter(name)
+
+Creates a "getter" for the property with the given `name` on the delegated
+object.
+
+## Delegate#setter(name)
+
+Creates a "setter" for the property with the given `name` on the delegated
+object.
+
+## Delegate#access(name)
+
+Creates an "accessor" (ie: both getter *and* setter) for the property with the
+given `name` on the delegated object.
+
+## Delegate#fluent(name)
+
+A unique type of "accessor" that works for a "fluent" API. When called as a
+getter, the method returns the expected value. However, if the method is called
+with a value, it will return itself so it can be chained. For example:
+
+```js
+delegate(proto, 'request')
+  .fluent('query')
+
+// getter
+var q = request.query();
+
+// setter (chainable)
+request
+  .query({ a: 1 })
+  .query({ b: 2 });
+```

+
+***Node-core streams for userland***
+
+[![NPM](https://nodei.co/npm/readable-stream.png?downloads=true&downloadRank=true)](https://nodei.co/npm/readable-stream/)
+[![NPM](https://nodei.co/npm-dl/readable-stream.png&months=6&height=3)](https://nodei.co/npm/readable-stream/)
+
+This package is a mirror of the Streams2 and Streams3 implementations in Node-core.
+
+If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core.
+
+**readable-stream** comes in two major versions, v1.0.x and v1.1.x. The former tracks the Streams2 implementation in Node 0.10, including bug-fixes and minor improvements as they are added. The latter tracks Streams3 as it develops in Node 0.11; we will likely see a v1.2.x branch for Node 0.12.
+
+**readable-stream** uses proper patch-level versioning so if you pin to `"~1.0.0"` you’ll get the latest Node 0.10 Streams2 implementation, including any fixes and minor non-breaking improvements. The patch-level versions of 1.0.x and 1.1.x should mirror the patch-level versions of Node-core releases. You should prefer the **1.0.x** releases for now and when you’re ready to start using Streams3, pin to `"~1.1.0"`

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+gauge
+=====
+
+A nearly stateless terminal based horizontal guage / progress bar.
+
+```javascript
+var Gauge = require("gauge")
+
+var gauge = new Gauge()
+
+gauge.show("test", 0.20)
+
+gauge.pulse("this")
+
+gauge.hide()
+```
+
+![](example.png)
+
+
+### `var gauge = new Gauge([options], [ansiStream])`
+
+* **options** – *(optional)* An option object. (See [below] for details.)
+* **ansiStream** – *(optional)* A stream that's been blessed by the [ansi]
+  module to include various commands for controlling the cursor in a terminal.
+
+[ansi]: https://www.npmjs.com/package/ansi
+[below]: #theme-objects
+
+Constructs a new gauge. Gauges are drawn on a single line, and are not drawn
+if the current terminal isn't a tty.
+
+If you resize your terminal in a way that can be detected then the gauge
+will be drawn at the new size. As a general rule, growing your terminal will
+be clean, but shrinking your terminal will result in cruft as we don't have
+enough information to know where what we wrote previously is now located.
+
+The **options** object can have the following properties, all of which are
+optional:
+
+* maxUpdateFrequency: defaults to 50 msec, the gauge will not be drawn more
+  than once in this period of time. This applies to `show` and `pulse`
+  calls, but if you `hide` and then `show` the gauge it will draw it
+  regardless of time since last draw.
+* theme: defaults to Gauge.unicode` if the terminal supports
+  unicode according to [has-unicode], otherwise it defaults to `Gauge.ascii`.
+  Details on the [theme object](#theme-objects) are documented elsewhere.
+* template: see [documentation elsewhere](#template-objects) for
+  defaults and details.
+
+[has-unicode]: https://www.npmjs.com/package/has-unicode
+
+If **ansiStream** isn't passed in, then one will be constructed from stderr
+with `ansi(process.stderr)`.
+
+### `gauge.show([name, [completed]])`
+
+* **name** – *(optional)* The name of the current thing contributing to progress. Defaults to the last value used, or "".
+* **completed** – *(optional)* The portion completed as a value between 0 and 1. Defaults to the last value used, or 0.
+
+If `process.stdout.isTTY` is false then this does nothing. If completed is 0
+and `gauge.pulse` has never been called, then similarly nothing will be printed.
+
+If `maxUpdateFrequency` msec haven't passed since the last call to `show` or
+`pulse` then similarly, nothing will be printed.  (Actually, the update is
+deferred until `maxUpdateFrequency` msec have passed and if nothing else has
+happened, the gauge update will happen.)
+
+### `gauge.hide()`
+
+Removes the gauge from the terminal.
+
+### `gauge.pulse([name])`
+
+* **name** – *(optional)* The specific thing that triggered this pulse
+
+Spins the spinner in the gauge to show output. If **name** is included then
+it will be combined with the last name passed to `gauge.show` using the
+subsection property of the theme (typically a right facing arrow).
+
+### `gauge.disable()`
+
+Hides the gauge and ignores further calls to `show` or `pulse`.
+
+### `gauge.enable()`
+
+Shows the gauge and resumes updating when `show` or `pulse` is called.
+
+### `gauge.setTheme(theme)`
+
+Change the active theme, will be displayed with the next show or pulse
+
+### `gauge.setTemplate(template)`
+
+Change the active template, will be displayed with the next show or pulse
+
+### Theme Objects
+
+There are two theme objects available as a part of the module, `Gauge.unicode` and `Gauge.ascii`.
+Theme objects have the follow properties:
+
+| Property   | Unicode | ASCII |
+| ---------- | ------- | ----- |
+| startgroup | ╢       | \|    |
+| endgroup   | ╟       | \|    |
+| complete   | █       | #     |
+| incomplete | ░       | -     |
+| spinner    | ▀▐▄▌    | -\\\|/ |
+| subsection | →       | ->    |
+
+*startgroup*, *endgroup* and *subsection* can be as many characters as you want.
+
+*complete* and *incomplete* should be a single character width each.
+
+*spinner* is a list of characters to use in turn when displaying an activity
+spinner.  The Gauge will spin as many characters as you give here.
+
+### Template Objects
+
+A template is an array of objects and strings that, after being evaluated,
+will be turned into the gauge line.  The default template is:
+
+```javascript

+  * `startgroup` – The `startgroup` property from the theme.
+  * `completionbar` – This progress bar itself
+  * `endgroup` – The `endgroup` property from the theme.
+* *separated* – If true, the element will be separated with spaces from things on
+  either side (and margins count as space, so it won't be indented), but only
+  if its included.
+* *maxLength* – The maximum length for this element. If its value is longer it
+  will be truncated.
+* *minLength* – The minimum length for this element. If its value is shorter it
+  will be padded according to the *align* value.
+* *align* – (Default: left) Possible values "left", "right" and "center". Works
+  as you'd expect from word processors.
+* *length* – Provides a single value for both *minLength* and *maxLength*. If both
+  *length* and *minLength or *maxLength* are specifed then the latter take precedence.

+
+If you have more than one thing going on that you want to track completion

+gauge
+=====
+
+A nearly stateless terminal based horizontal guage / progress bar.
+
+```javascript
+var Gauge = require("gauge")
+
+var gauge = new Gauge()
+
+gauge.show("test", 0.20)
+
+gauge.pulse("this")
+
+gauge.hide()
+```
+
+![](example.png)
+
+
+### `var gauge = new Gauge([options], [ansiStream])`
+
+* **options** – *(optional)* An option object. (See [below] for details.)
+* **ansiStream** – *(optional)* A stream that's been blessed by the [ansi]
+  module to include various commands for controlling the cursor in a terminal.
+
+[ansi]: https://www.npmjs.com/package/ansi
+[below]: #theme-objects
+
+Constructs a new gauge. Gauges are drawn on a single line, and are not drawn
+if the current terminal isn't a tty.
+
+The **options** object can have the following properties, all of which are
+optional:
+
+* maxUpdateFrequency: defaults to 50 msec, the gauge will not be drawn more
+  than once in this period of time. This applies to `show` and `pulse`
+  calls, but if you `hide` and then `show` the gauge it will draw it
+  regardless of time since last draw.
+* theme: defaults to Gauge.unicode` if the terminal supports
+  unicode according to [has-unicode], otherwise it defaults to `Gauge.ascii`.
+  Details on the [theme object](#theme-objects) are documented elsewhere.
+* template: see [documentation elsewhere](#template-objects) for
+  defaults and details.
+
+[has-unicode]: https://www.npmjs.com/package/has-unicode
+
+If **ansiStream** isn't passed in, then one will be constructed from stderr
+with `ansi(process.stderr)`.
+
+### `gauge.show([name, [completed]])`
+
+* **name** – *(optional)* The name of the current thing contributing to progress. Defaults to the last value used, or "".
+* **completed** – *(optional)* The portion completed as a value between 0 and 1. Defaults to the last value used, or 0.
+
+If `process.stdout.isTTY` is false then this does nothing. If completed is 0
+and `gauge.pulse` has never been called, then similarly nothing will be printed.
+
+If `maxUpdateFrequency` msec haven't passed since the last call to `show` or
+`pulse` then similarly, nothing will be printed.  (Actually, the update is
+deferred until `maxUpdateFrequency` msec have passed and if nothing else has
+happened, the gauge update will happen.)
+
+### `gauge.hide()`
+
+Removes the gauge from the terminal.
+
+### `gauge.pulse([name])`
+
+* **name** – *(optional)* The specific thing that triggered this pulse
+
+Spins the spinner in the gauge to show output. If **name** is included then
+it will be combined with the last name passed to `gauge.show` using the
+subsection property of the theme (typically a right facing arrow).
+
+### `gauge.disable()`
+
+Hides the gauge and ignores further calls to `show` or `pulse`.
+
+### `gauge.enable()`
+
+Shows the gauge and resumes updating when `show` or `pulse` is called.
+
+### `gauge.setTheme(theme)`
+
+Change the active theme, will be displayed with the next show or pulse
+
+### `gauge.setTemplate(template)`
+
+Change the active template, will be displayed with the next show or pulse
+
+### Theme Objects
+
+There are two theme objects available as a part of the module, `Gauge.unicode` and `Gauge.ascii`.
+Theme objects have the follow properties:
+
+| Property   | Unicode | ASCII |
+| ---------- | ------- | ----- |
+| startgroup | ╢       | \|    |
+| endgroup   | ╟       | \|    |
+| complete   | █       | #     |
+| incomplete | ░       | -     |
+| spinner    | ▀▐▄▌    | -\\\|/ |
+| subsection | →       | ->    |
+
+*startgroup*, *endgroup* and *subsection* can be as many characters as you want.
+
+*complete* and *incomplete* should be a single character width each.
+
+*spinner* is a list of characters to use in turn when displaying an activity
+spinner.  The Gauge will spin as many characters as you give here.
+
+### Template Objects
+
+A template is an array of objects and strings that, after being evaluated,
+will be turned into the gauge line.  The default template is:
+
+```javascript
+[
+    {type: "name", separated: true, maxLength: 25, minLength: 25, align: "left"},
+    {type: "spinner", separated: true},
+    {type: "startgroup"},
+    {type: "completionbar"},
+    {type: "endgroup"}
+]
+```
+
+The various template elements can either be **plain strings**, in which case they will
+be be included verbatum in the output.
+
+If the template element is an object, it can have the following keys:
+
+* *type* can be:
+  * `name` – The most recent name passed to `show`; if this is in response to a
+    `pulse` then the name passed to `pulse` will be appended along with the
+    subsection property from the theme.
+  * `spinner` – If you've ever called `pulse` this will be one of the characters
+    from the spinner property of the theme.
+  * `startgroup` – The `startgroup` property from the theme.
+  * `completionbar` – This progress bar itself
+  * `endgroup` – The `endgroup` property from the theme.
+* *separated* – If true, the element will be separated with spaces from things on
+  either side (and margins count as space, so it won't be indented), but only
+  if its included.
+* *maxLength* – The maximum length for this element. If its value is longer it
+  will be truncated.
+* *minLength* – The minimum length for this element. If its value is shorter it
+  will be padded according to the *align* value.
+* *align* – (Default: left) Possible values "left", "right" and "center". Works
+  as you'd expect from word processors.
+* *length* – Provides a single value for both *minLength* and *maxLength*. If both
+  *length* and *minLength or *maxLength* are specifed then the latter take precedence.
+
+### Tracking Completion

+If you have more than one thing going on that you want to track completion
+of, you may find the related [are-we-there-yet] helpful.  It's `change`
+event can be wired up to the `show` method to get a more traditional
