+# npm-bundled
+
+Run this in a node package, and it'll tell you which things in
+node_modules are bundledDependencies, or transitive dependencies of
+bundled dependencies.
+
+## USAGE
+
+To get the list of deps at the top level that are bundled (or
+transitive deps of a bundled dep) run this:
+
+```js
+const bundled = require('npm-bundled')
+
+// async version
+bundled({ path: '/path/to/pkg/defaults/to/cwd'}, (er, list) => {
+  // er means it had an error, which is _hella_ weird
+  // list is a list of package names, like `fooblz` or `@corp/blerg`
+  // the might not all be deps of the top level, because transitives
+})
+
+// async promise version
+bundled({ path: '/path/to/pkg/defaults/to/cwd'}).then(list => {
+  // so promisey!
+  // actually the callback version returns a promise, too, it just
+  // attaches the supplied callback to the promise
+})
+
+// sync version, throws if there's an error
+const list = bundled({ path: '/path/to/pkg/defaults/to/cwd'})
+```
+
+That's basically all you need to know.  If you care to dig into it,
+you can also use the `bundled.Walker` and `bundled.WalkerSync`
+classes to get fancy.
+
+This library does not write anything to the filesystem, but it _may_
+have undefined behavior if the structure of `node_modules` changes
+while it's reading deps.
+
+All symlinks are followed.  This means that it can lead to surprising
+results if a symlinked bundled dependency has a missing dependency
+that is satisfied at the top level.  Since package creation resolves
+symlinks as well, this is an edge case where package creation and
+development environment are not going to be aligned, and is best
+avoided.
