+# `@actions/core`
+
+> Core functions for setting results, logging, registering secrets and exporting variables across actions
+
+## Usage
+
+#### Inputs/Outputs
+
+You can use this library to get inputs or set outputs:
+
+```js
+const core = require('@actions/core');
+
+const myInput = core.getInput('inputName', { required: true });
+
+// Do stuff
+
+core.setOutput('outputKey', 'outputVal');
+```
+
+#### Exporting variables
+
+You can also export variables for future steps. Variables get set in the environment.
+
+```js
+const core = require('@actions/core');
+
+// Do stuff
+
+core.exportVariable('envVar', 'Val');
+```
+
+#### PATH Manipulation
+
+You can explicitly add items to the path for all remaining steps in a workflow:
+
+```js
+const core = require('@actions/core');
+
+core.addPath('pathToTool');
+```
+
+#### Exit codes
+
+You should use this library to set the failing exit code for your action:
+
+```js
+const core = require('@actions/core');
+
+try {
+  // Do stuff
+}
+catch (err) {
+  // setFailed logs the message and sets a failing exit code
+  core.setFailed(`Action failed with error ${err}`);
+}
+
+```
+
+#### Logging
+
+Finally, this library provides some utilities for logging. Note that debug logging is hidden from the logs by default. This behavior can be toggled by enabling the [Step Debug Logs](../../docs/action-debugging.md#step-debug-logs).
+
+```js
+const core = require('@actions/core');
+
+const myInput = core.getInput('input');
+try {
+  core.debug('Inside try block');
+  
+  if (!myInput) {
+    core.warning('myInput was not set');
+  }
+  
+  // Do stuff
+}
+catch (err) {
+  core.error(`Error ${err}, action may still succeed though`);
+}
+```
+
+This library can also wrap chunks of output in foldable groups.
+
+```js
+const core = require('@actions/core')
+
+// Manually wrap output
+core.startGroup('Do some function')
+doSomeFunction()
+core.endGroup()
+
+// Wrap an asynchronous function call
+const result = await core.group('Do something async', async () => {
+  const response = await doSomeHTTPRequest()
+  return response
+})
+```

+# balanced-match
+
+Match balanced string pairs, like `{` and `}` or `<b>` and `</b>`. Supports regular expressions as well!
+
+[![build status](https://secure.travis-ci.org/juliangruber/balanced-match.svg)](http://travis-ci.org/juliangruber/balanced-match)
+[![downloads](https://img.shields.io/npm/dm/balanced-match.svg)](https://www.npmjs.org/package/balanced-match)
+
+[![testling badge](https://ci.testling.com/juliangruber/balanced-match.png)](https://ci.testling.com/juliangruber/balanced-match)
+
+## Example
+
+Get the first matching pair of braces:
+
+```js
+var balanced = require('balanced-match');
+
+console.log(balanced('{', '}', 'pre{in{nested}}post'));
+console.log(balanced('{', '}', 'pre{first}between{second}post'));
+console.log(balanced(/\s+\{\s+/, /\s+\}\s+/, 'pre  {   in{nest}   }  post'));
+```
+
+The matches are:
+
+```bash
+$ node example.js
+{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
+{ start: 3,
+  end: 9,
+  pre: 'pre',
+  body: 'first',
+  post: 'between{second}post' }
+{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: 'post' }
+```
+
+## API
+
+### var m = balanced(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+object with those keys:
+
+* **start** the index of the first match of `a`
+* **end** the index of the matching `b`
+* **pre** the preamble, `a` and `b` not included
+* **body** the match, `a` and `b` not included
+* **post** the postscript, `a` and `b` not included
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']` and `{a}}` will match `['', 'a', '}']`.
+
+### var r = balanced.range(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+array with indexes: `[ <a index>, <b index> ]`.
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.

+
+## API
+
+```js
+var expand = require('brace-expansion');
+```
+
+### var expanded = expand(str)
+
+Return an array of all possible and valid expansions of `str`. If none are
+found, `[str]` is returned.
+
+Valid expansions are:
+
+```js
+/^(.*,)+(.+)?$/
+// {a,b,...}
+```
+
+A comma separated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+A numeric sequence from `x` to `y` inclusive, with optional increment.
+If `x` or `y` start with a leading `0`, all the numbers will be padded
+to have equal length. Negative numbers and backwards iteration work too.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+An alphabetic sequence from `x` to `y` inclusive, with optional increment.
+`x` and `y` must be exactly one character, and if given, `incr` must be a
+number.
+
+For compatibility reasons, the string `${` is not eligible for brace expansion.

+# fs.realpath
+
+A backwards-compatible fs.realpath for Node v6 and above
+
+In Node v6, the JavaScript implementation of fs.realpath was replaced
+with a faster (but less resilient) native implementation.  That raises
+new and platform-specific errors and cannot handle long or excessively
+symlink-looping paths.
+
+This module handles those cases by detecting the new errors and
+falling back to the JavaScript implementation.  On versions of Node
+prior to v6, it has no effect.
+
+## USAGE
+
+```js
+var rp = require('fs.realpath')
+
+// async version
+rp.realpath(someLongAndLoopingPath, function (er, real) {
+  // the ELOOP was handled, but it was a bit slower
+})
+
+// sync version
+var real = rp.realpathSync(someLongAndLoopingPath)
+
+// monkeypatch at your own risk!
+// This replaces the fs.realpath/fs.realpathSync builtins
+rp.monkeypatch()
+
+// un-do the monkeypatching
+rp.unmonkeypatch()
+```

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![](logo/glob.png)
+
+## Usage
+
+Install with npm
+
+```
+npm i glob
+```
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array<String>}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array<String>}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `absolute` Set to true to always receive absolute paths for matched
+  files.  Unlike `realpath`, this also affects the values returned in
+  the `match` event.
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+
+A dictionary of file extensions and associated module loaders.
+
+## What is it
+This is used by [Liftoff](http://github.com/tkellen/node-liftoff) to automatically require dependencies for configuration files, and by [rechoir](http://github.com/tkellen/node-rechoir) for registering module loaders.
+
+## API
+
+### extensions
+Map file types to modules which provide a [require.extensions] loader.
+

+
+### jsVariants
+Same as above, but only include the extensions which are javascript variants.
+
+## How to use it
+
+Consumers should use the exported `extensions` or `jsVariants` object to determine which module should be loaded for a given extension. If a matching extension is found, consumers should do the following:
+
+1. If the value is null, do nothing.
+
+2. If the value is a string, try to require it.
+
+3. If the value is an object, try to require the `module` property. If successful, the `register` property (a function) should be called with the module passed as the first argument.
+
+4. If the value is an array, iterate over it, attempting step #2 or #3 until one of the attempts does not throw.

+# minimatch
+
+A minimal matching utility.
+
+[![Build Status](https://secure.travis-ci.org/isaacs/minimatch.svg)](http://travis-ci.org/isaacs/minimatch)
+
+
+This is the matching library used internally by npm.
+
+It works by converting glob expressions into JavaScript `RegExp`
+objects.
+
+## Usage
+
+```javascript
+var minimatch = require("minimatch")
+
+minimatch("bar.foo", "*.foo") // true!
+minimatch("bar.foo", "*.bar") // false!
+minimatch("bar.foo", "*.+(bar|foo)", { debug: true }) // true, and noisy!
+```
+
+## Features
+
+Supports these glob features:
+
+* Brace Expansion
+* Extended glob matching
+* "Globstar" `**` matching
+
+See:
+
+* `man sh`
+* `man bash`
+* `man 3 fnmatch`
+* `man 5 gitignore`
+
+## Minimatch Class
+
+Create a minimatch object by instantiating the `minimatch.Minimatch` class.
+
+```javascript
+var Minimatch = require("minimatch").Minimatch
+var mm = new Minimatch(pattern, options)
+```
+
+### Properties
+
+* `pattern` The original pattern the minimatch object represents.
+* `options` The options supplied to the constructor.
+* `set` A 2-dimensional array of regexp or string expressions.
+  Each row in the
+  array corresponds to a brace-expanded pattern.  Each item in the row
+  corresponds to a single path-part.  For example, the pattern
+  `{a,b/c}/d` would expand to a set of patterns like:
+
+        [ [ a, d ]
+        , [ b, c, d ] ]
+
+    If a portion of the pattern doesn't have any "magic" in it
+    (that is, it's something like `"foo"` rather than `fo*o?`), then it
+    will be left as a string rather than converted to a regular
+    expression.
+
+* `regexp` Created by the `makeRe` method.  A single regular expression
+  expressing the entire pattern.  This is useful in cases where you wish
+  to use the pattern somewhat like `fnmatch(3)` with `FNM_PATH` enabled.
+* `negate` True if the pattern is negated.
+* `comment` True if the pattern is a comment.
+* `empty` True if the pattern is `""`.
+
+### Methods
+
+* `makeRe` Generate the `regexp` member if necessary, and return it.
+  Will return `false` if the pattern is invalid.
+* `match(fname)` Return true if the filename matches the pattern, or
+  false otherwise.
+* `matchOne(fileArray, patternArray, partial)` Take a `/`-split
+  filename, and match it against a single row in the `regExpSet`.  This
+  method is mainly for internal use, but is exposed so that it can be
+  used by a glob-walker that needs to avoid excessive filesystem calls.
+
+All other methods are internal, and will be called as necessary.
+
+### minimatch(path, pattern, options)
+
+Main export.  Tests a path against the pattern using the options.
+
+```javascript
+var isJS = minimatch(file, "*.js", { matchBase: true })
+```
+
+### minimatch.filter(pattern, options)
+
+Returns a function that tests its
+supplied argument, suitable for use with `Array.filter`.  Example:
+
+```javascript
+var javascripts = fileList.filter(minimatch.filter("*.js", {matchBase: true}))
+```
+
+### minimatch.match(list, pattern, options)
+
+Match against the list of
+files, in the style of fnmatch or glob.  If nothing is matched, and
+options.nonull is set, then return a list containing the pattern itself.
+
+```javascript
+var javascripts = minimatch.match(fileList, "*.js", {matchBase: true}))
+```
+
+### minimatch.makeRe(pattern, options)
+
+Make a regular expression object from the pattern.
+
+## Options
+
+All options are `false` by default.
+
+### debug
+
+Dump a ton of stuff to stderr.
+
+### nobrace
+
+Do not expand `{a,b}` and `{1..3}` brace sets.
+
+### noglobstar
+
+Disable `**` matching against multiple folder names.
+
+### dot
+
+Allow patterns to match filenames starting with a period, even if
+the pattern does not explicitly have a period in that spot.
+
+Note that by default, `a/**/b` will **not** match `a/.d/b`, unless `dot`
+is set.
+
+### noext
+
+Disable "extglob" style patterns like `+(a|b)`.
+
+### nocase
+
+Perform a case-insensitive match.
+
+### nonull
+
+When a match is not found by `minimatch.match`, return a list containing
+the pattern itself if this option is set.  When not set, an empty list
+is returned if there are no matches.
+
+### matchBase
+
+If set, then patterns without slashes will be matched
+against the basename of the path if it contains slashes.  For example,
+`a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`.
+
+### nocomment
+
+Suppress the behavior of treating `#` at the start of a pattern as a
+comment.
+
+### nonegate
+
+Suppress the behavior of treating a leading `!` character as negation.
+
+### flipNegate
+
+Returns from negate expressions the same as if they were not negated.
+(Ie, true on a hit, false on a miss.)
+
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between minimatch and other
+implementations, and are intentional.
+
+If the pattern starts with a `!` character, then it is negated.  Set the
+`nonegate` flag to suppress this behavior, and treat leading `!`
+characters normally.  This is perhaps relevant if you wish to start the
+pattern with a negative extglob pattern like `!(a|B)`.  Multiple `!`
+characters at the start of a pattern will negate the pattern multiple
+times.
+
+If a pattern starts with `#`, then it is treated as a comment, and
+will not match anything.  Use `\#` to match a literal `#` at the
+start of a line, or set the `nocomment` flag to suppress this behavior.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.1, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then minimatch.match returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`minimatch.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.

+# once
+
+Only call a function once.
+
+## usage
+
+```javascript
+var once = require('once')
+
+function load (file, cb) {
+  cb = once(cb)
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Or add to the Function.prototype in a responsible way:
+
+```javascript
+// only has to be done once
+require('once').proto()
+
+function load (file, cb) {
+  cb = cb.once()
+  loader.load('file')
+  loader.once('load', cb)
+  loader.once('error', cb)
+}
+```
+
+Ironically, the prototype feature makes this module twice as
+complicated as necessary.
+
+To check whether you function has been called, use `fn.called`. Once the
+function is called for the first time the return value of the original
+function is saved in `fn.value` and subsequent calls will continue to
+return this value.
+
+```javascript
+var once = require('once')
+
+function load (cb) {
+  cb = once(cb)
+  var stream = createStream()
+  stream.once('data', cb)
+  stream.once('end', function () {
+    if (!cb.called) cb(new Error('not found'))
+  })
+}
+```
+
+## `once.strict(func)`
+
+Throw an error if the function is called twice.
+
+Some functions are expected to be called only once. Using `once` for them would
+potentially hide logical errors.
+
+In the example below, the `greet` function has to call the callback only once:
+
+```javascript
+function greet (name, cb) {
+  // return is missing from the if statement
+  // when no name is passed, the callback is called twice
+  if (!name) cb('Hello anonymous')
+  cb('Hello ' + name)
+}
+
+function log (msg) {
+  console.log(msg)
+}
+
+// this will print 'Hello anonymous' but the logical error will be missed
+greet(null, once(msg))
+
+// once.strict will print 'Hello anonymous' and throw an error when the callback will be called the second time
+greet(null, once.strict(msg))
+```

+# rechoir [![Build Status](https://secure.travis-ci.org/tkellen/js-rechoir.png)](http://travis-ci.org/tkellen/js-rechoir)
+> Require any supported file as a node module.
+
+[![NPM](https://nodei.co/npm/rechoir.png)](https://nodei.co/npm/rechoir/)
+
+## What is it?
+This module, in conjunction with [interpret]-like objects can register any file type the npm ecosystem has a module loader for. This library is a dependency of [Liftoff].
+
+## API
+
+### prepare(config, filepath, requireFrom)
+Look for a module loader associated with the provided file and attempt require it.  If necessary, run any setup required to inject it into [require.extensions](http://nodejs.org/api/globals.html#globals_require_extensions).
+
+`config` An [interpret]-like configuration object.  
+
+`filepath` A file whose type you'd like to register a module loader for.
+
+`requireFrom` An optional path to start searching for the module required to load the requested file.  Defaults to the directory of `filepath`.
+
+If calling this method is successful (aka: it doesn't throw), you can now require files of the type you requested natively.
+
+An error with a `failures` property will be thrown if the module loader(s) configured for a given extension cannot be registered.
+
+If a loader is already registered, this will simply return `true`.
+
+**Note:** While rechoir will automatically load and register transpilers like `coffee-script`, you must provide a local installation. The transpilers are **not** bundled with this module.
+
+#### Usage
+```js
+const config = require('interpret').extensions;
+const rechoir = require('rechoir');
+rechoir.prepare(config, './test/fixtures/test.coffee');
+rechoir.prepare(config, './test/fixtures/test.csv');
+rechoir.prepare(config, './test/fixtures/test.toml');
+
+console.log(require('./test/fixtures/test.coffee'));
+console.log(require('./test/fixtures/test.csv'));
+console.log(require('./test/fixtures/test.toml'));
+```

+
+## 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);
+        });
+    },
+    isDirectory: function isDirectory(dir, cb) {

+        });
+    },
+    moduleDirectory: 'node_modules',

+```
+
+## resolve.sync(id, opts)
+
+Synchronously resolve the module path string `id`, returning the result and
+throwing an error when `id` can't be resolved.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* 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)
+
+* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`

+# ShellJS - Unix shell commands for Node.js
+
+[![Travis](https://img.shields.io/travis/shelljs/shelljs/master.svg?style=flat-square&label=unix)](https://travis-ci.org/shelljs/shelljs)
+[![AppVeyor](https://img.shields.io/appveyor/ci/shelljs/shelljs/master.svg?style=flat-square&label=windows)](https://ci.appveyor.com/project/shelljs/shelljs/branch/master)

+[![npm downloads](https://img.shields.io/npm/dm/shelljs.svg?style=flat-square)](https://www.npmjs.com/package/shelljs)
+
+ShellJS is a portable **(Windows/Linux/OS X)** implementation of Unix shell
+commands on top of the Node.js API. You can use it to eliminate your shell
+script's dependency on Unix while still keeping its familiar and powerful
+commands. You can also install it globally so you can run it from outside Node
+projects - say goodbye to those gnarly Bash scripts!
+
+ShellJS is proudly tested on every node release since `v4`!
+
+The project is [unit-tested](http://travis-ci.org/shelljs/shelljs) and battle-tested in projects like:
+
++ [Firebug](http://getfirebug.com/) - Firefox's infamous debugger
++ [JSHint](http://jshint.com) & [ESLint](http://eslint.org/) - popular JavaScript linters
++ [Zepto](http://zeptojs.com) - jQuery-compatible JavaScript library for modern browsers
++ [Yeoman](http://yeoman.io/) - Web application stack and development tool
++ [Deployd.com](http://deployd.com) - Open source PaaS for quick API backend generation
++ And [many more](https://npmjs.org/browse/depended/shelljs).
+
+If you have feedback, suggestions, or need help, feel free to post in our [issue
+tracker](https://github.com/shelljs/shelljs/issues).
+
+Think ShellJS is cool? Check out some related projects in our [Wiki
+page](https://github.com/shelljs/shelljs/wiki)!
+
+Upgrading from an older version? Check out our [breaking
+changes](https://github.com/shelljs/shelljs/wiki/Breaking-Changes) page to see
+what changes to watch out for while upgrading.
+
+## Command line use
+
+If you just want cross platform UNIX commands, checkout our new project
+[shelljs/shx](https://github.com/shelljs/shx), a utility to expose `shelljs` to
+the command line.
+
+For example:
+
+```
+$ shx mkdir -p foo
+$ shx touch foo/bar.txt
+$ shx rm -rf foo
+```
+
+## Plugin API
+
+ShellJS now supports third-party plugins! You can learn more about using plugins
+and writing your own ShellJS commands in [the
+wiki](https://github.com/shelljs/shelljs/wiki/Using-ShellJS-Plugins).
+
+## A quick note about the docs
+
+For documentation on all the latest features, check out our
+[README](https://github.com/shelljs/shelljs). To read docs that are consistent
+with the latest release, check out [the npm
+page](https://www.npmjs.com/package/shelljs) or
+[shelljs.org](http://documentup.com/shelljs/shelljs).
+
+## Installing
+
+Via npm:
+
+```bash
+$ npm install [-g] shelljs
+```
+
+## Examples
+
+```javascript
+var shell = require('shelljs');
+
+if (!shell.which('git')) {
+  shell.echo('Sorry, this script requires git');
+  shell.exit(1);
+}
+
+// Copy files to release dir
+shell.rm('-rf', 'out/Release');
+shell.cp('-R', 'stuff/', 'out/Release');
+
+// Replace macros in each .js file
+shell.cd('lib');
+shell.ls('*.js').forEach(function (file) {
+  shell.sed('-i', 'BUILD_VERSION', 'v0.1.2', file);
+  shell.sed('-i', /^.*REMOVE_THIS_LINE.*$/, '', file);
+  shell.sed('-i', /.*REPLACE_LINE_WITH_MACRO.*\n/, shell.cat('macro.js'), file);
+});
+shell.cd('..');
+
+// Run external tool synchronously
+if (shell.exec('git commit -am "Auto-commit"').code !== 0) {
+  shell.echo('Error: Git commit failed');
+  shell.exit(1);
+}
+```
+
+## Exclude options
+
+If you need to pass a parameter that looks like an option, you can do so like:
+
+```js
+shell.grep('--', '-v', 'path/to/file'); // Search for "-v", no grep options
+
+shell.cp('-R', '-dir', 'outdir'); // If already using an option, you're done
+```
+
+## Global vs. Local
+
+We no longer recommend using a global-import for ShellJS (i.e.
+`require('shelljs/global')`). While still supported for convenience, this
+pollutes the global namespace, and should therefore only be used with caution.
+
+Instead, we recommend a local import (standard for npm packages):
+
+```javascript
+var shell = require('shelljs');
+shell.echo('hello world');
+```
+
+<!-- DO NOT MODIFY BEYOND THIS POINT - IT'S AUTOMATICALLY GENERATED -->
+
+
+## Command reference
+
+
+All commands run synchronously, unless otherwise stated.
+All commands accept standard bash globbing characters (`*`, `?`, etc.),
+compatible with the [node `glob` module](https://github.com/isaacs/node-glob).
+
+For less-commonly used commands and features, please check out our [wiki
+page](https://github.com/shelljs/shelljs/wiki).
+
+
+### cat([options,] file [, file ...])
+### cat([options,] file_array)
+
+Available options:
+
++ `-n`: number all output lines
+
+Examples:
+
+```javascript
+var str = cat('file*.txt');
+var str = cat('file1', 'file2');
+var str = cat(['file1', 'file2']); // same as above
+```
+
+Returns a string containing the given file, or a concatenated string
+containing the files if more than one file is given (a new line character is
+introduced between each file).
+
+
+### cd([dir])
+
+Changes to directory `dir` for the duration of the script. Changes to home
+directory if no argument is supplied.
+
+
+### chmod([options,] octal_mode || octal_string, file)
+### chmod([options,] symbolic_mode, file)
+
+Available options:
+
++ `-v`: output a diagnostic for every file processed
++ `-c`: like verbose, but report only when a change is made
++ `-R`: change files and directories recursively
+
+Examples:
+
+```javascript
+chmod(755, '/Users/brandon');
+chmod('755', '/Users/brandon'); // same as above
+chmod('u+x', '/Users/brandon');
+chmod('-R', 'a-w', '/Users/brandon');
+```
+
+Alters the permissions of a file or directory by either specifying the
+absolute permissions in octal form or expressing the changes in symbols.
+This command tries to mimic the POSIX behavior as much as possible.
+Notable exceptions:
+
++ In symbolic modes, `a-r` and `-r` are identical.  No consideration is
+  given to the `umask`.
++ There is no "quiet" option, since default behavior is to run silent.
+
+
+### cp([options,] source [, source ...], dest)
+### cp([options,] source_array, dest)
+
+Available options:
+
++ `-f`: force (default behavior)
++ `-n`: no-clobber
++ `-u`: only copy if `source` is newer than `dest`
++ `-r`, `-R`: recursive
++ `-L`: follow symlinks
++ `-P`: don't follow symlinks
+
+Examples:
+
+```javascript
+cp('file1', 'dir1');
+cp('-R', 'path/to/dir/', '~/newCopy/');
+cp('-Rf', '/tmp/*', '/usr/local/*', '/home/tmp');
+cp('-Rf', ['/tmp/*', '/usr/local/*'], '/home/tmp'); // same as above
+```
+
+Copies files.
+
+
+### pushd([options,] [dir | '-N' | '+N'])
+
+Available options:
+
++ `-n`: Suppresses the normal change of directory when adding directories to the stack, so that only the stack is manipulated.
++ `-q`: Supresses output to the console.
+
+Arguments:
+
++ `dir`: Sets the current working directory to the top of the stack, then executes the equivalent of `cd dir`.
++ `+N`: Brings the Nth directory (counting from the left of the list printed by dirs, starting with zero) to the top of the list by rotating the stack.
++ `-N`: Brings the Nth directory (counting from the right of the list printed by dirs, starting with zero) to the top of the list by rotating the stack.
+
+Examples:
+
+```javascript
+// process.cwd() === '/usr'
+pushd('/etc'); // Returns /etc /usr
+pushd('+1');   // Returns /usr /etc
+```
+
+Save the current directory on the top of the directory stack and then `cd` to `dir`. With no arguments, `pushd` exchanges the top two directories. Returns an array of paths in the stack.
+
+
+### popd([options,] ['-N' | '+N'])
+
+Available options:
+
++ `-n`: Suppress the normal directory change when removing directories from the stack, so that only the stack is manipulated.
++ `-q`: Supresses output to the console.
+
+Arguments:
+
++ `+N`: Removes the Nth directory (counting from the left of the list printed by dirs), starting with zero.
++ `-N`: Removes the Nth directory (counting from the right of the list printed by dirs), starting with zero.
+
+Examples:
+
+```javascript
+echo(process.cwd()); // '/usr'
+pushd('/etc');       // '/etc /usr'
+echo(process.cwd()); // '/etc'
+popd();              // '/usr'
+echo(process.cwd()); // '/usr'
+```
+
+When no arguments are given, `popd` removes the top directory from the stack and performs a `cd` to the new top directory. The elements are numbered from 0, starting at the first directory listed with dirs (i.e., `popd` is equivalent to `popd +0`). Returns an array of paths in the stack.
+
+
+### dirs([options | '+N' | '-N'])
+
+Available options:
+
++ `-c`: Clears the directory stack by deleting all of the elements.
++ `-q`: Supresses output to the console.
+
+Arguments:
+
++ `+N`: Displays the Nth directory (counting from the left of the list printed by dirs when invoked without options), starting with zero.
++ `-N`: Displays the Nth directory (counting from the right of the list printed by dirs when invoked without options), starting with zero.
+
+Display the list of currently remembered directories. Returns an array of paths in the stack, or a single path if `+N` or `-N` was specified.
+
+See also: `pushd`, `popd`
+
+
+### echo([options,] string [, string ...])
+
+Available options:
+
++ `-e`: interpret backslash escapes (default)
++ `-n`: remove trailing newline from output
+
+Examples:
+
+```javascript
+echo('hello world');
+var str = echo('hello world');
+echo('-n', 'no newline at end');
+```
+
+Prints `string` to stdout, and returns string with additional utility methods
+like `.to()`.
+
+
+### exec(command [, options] [, callback])
+
+Available options:
+
++ `async`: Asynchronous execution. If a callback is provided, it will be set to
+  `true`, regardless of the passed value (default: `false`).
++ `silent`: Do not echo program output to console (default: `false`).
++ `encoding`: Character encoding to use. Affects the values returned to stdout and stderr, and
+  what is written to stdout and stderr when not in silent mode (default: `'utf8'`).
++ and any option available to Node.js's
+  [`child_process.exec()`](https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback)
+
+Examples:
+
+```javascript
+var version = exec('node --version', {silent:true}).stdout;
+
+var child = exec('some_long_running_process', {async:true});
+child.stdout.on('data', function(data) {
+  /* ... do something with data ... */
+});
+
+exec('some_long_running_process', function(code, stdout, stderr) {
+  console.log('Exit code:', code);
+  console.log('Program output:', stdout);
+  console.log('Program stderr:', stderr);
+});
+```
+
+Executes the given `command` _synchronously_, unless otherwise specified.  When in synchronous
+mode, this returns a `ShellString` (compatible with ShellJS v0.6.x, which returns an object
+of the form `{ code:..., stdout:... , stderr:... }`). Otherwise, this returns the child process
+object, and the `callback` receives the arguments `(code, stdout, stderr)`.
+
+Not seeing the behavior you want? `exec()` runs everything through `sh`
+by default (or `cmd.exe` on Windows), which differs from `bash`. If you
+need bash-specific behavior, try out the `{shell: 'path/to/bash'}` option.
+
+
+### find(path [, path ...])
+### find(path_array)
+
+Examples:
+
+```javascript
+find('src', 'lib');
+find(['src', 'lib']); // same as above
+find('.').filter(function(file) { return file.match(/\.js$/); });
+```
+
+Returns array of all files (however deep) in the given paths.
+
+The main difference from `ls('-R', path)` is that the resulting file names
+include the base directories (e.g., `lib/resources/file1` instead of just `file1`).
+
+
+### grep([options,] regex_filter, file [, file ...])
+### grep([options,] regex_filter, file_array)
+
+Available options:
+
++ `-v`: Invert `regex_filter` (only print non-matching lines).
++ `-l`: Print only filenames of matching files.
++ `-i`: Ignore case.
+
+Examples:
+
+```javascript
+grep('-v', 'GLOBAL_VARIABLE', '*.js');
+grep('GLOBAL_VARIABLE', '*.js');
+```
+
+Reads input string from given files and returns a string containing all lines of the
+file that match the given `regex_filter`.
+
+
+### head([{'-n': \<num\>},] file [, file ...])
+### head([{'-n': \<num\>},] file_array)
+
+Available options:
+
++ `-n <num>`: Show the first `<num>` lines of the files
+
+Examples:
+
+```javascript
+var str = head({'-n': 1}, 'file*.txt');
+var str = head('file1', 'file2');
+var str = head(['file1', 'file2']); // same as above
+```
+
+Read the start of a file.
+
+
+### ln([options,] source, dest)
+
+Available options:
+
++ `-s`: symlink
++ `-f`: force
+
+Examples:
+
+```javascript
+ln('file', 'newlink');
+ln('-sf', 'file', 'existing');
+```
+
+Links `source` to `dest`. Use `-f` to force the link, should `dest` already exist.
+
+
+### ls([options,] [path, ...])
+### ls([options,] path_array)
+
+Available options:
+
++ `-R`: recursive
++ `-A`: all files (include files beginning with `.`, except for `.` and `..`)
++ `-L`: follow symlinks
++ `-d`: list directories themselves, not their contents
++ `-l`: list objects representing each file, each with fields containing `ls
+        -l` output fields. See
+        [`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats)
+        for more info
+
+Examples:
+
+```javascript
+ls('projs/*.js');
+ls('-R', '/users/me', '/tmp');
+ls('-R', ['/users/me', '/tmp']); // same as above
+ls('-l', 'file.txt'); // { name: 'file.txt', mode: 33188, nlink: 1, ...}
+```
+
+Returns array of files in the given `path`, or files in
+the current directory if no `path` is  provided.
+
+
+### mkdir([options,] dir [, dir ...])
+### mkdir([options,] dir_array)
+
+Available options:
+
++ `-p`: full path (and create intermediate directories, if necessary)
+
+Examples:
+
+```javascript
+mkdir('-p', '/tmp/a/b/c/d', '/tmp/e/f/g');
+mkdir('-p', ['/tmp/a/b/c/d', '/tmp/e/f/g']); // same as above
+```
+
+Creates directories.
+
+
+### mv([options ,] source [, source ...], dest')
+### mv([options ,] source_array, dest')
+
+Available options:
+
++ `-f`: force (default behavior)
++ `-n`: no-clobber
+
+Examples:
+
+```javascript
+mv('-n', 'file', 'dir/');
+mv('file1', 'file2', 'dir/');
+mv(['file1', 'file2'], 'dir/'); // same as above
+```
+
+Moves `source` file(s) to `dest`.
+
+
+### pwd()
+
+Returns the current directory.
+
+
+### rm([options,] file [, file ...])
+### rm([options,] file_array)
+
+Available options:
+
++ `-f`: force
++ `-r, -R`: recursive
+
+Examples:
+
+```javascript
+rm('-rf', '/tmp/*');
+rm('some_file.txt', 'another_file.txt');
+rm(['some_file.txt', 'another_file.txt']); // same as above
+```
+
+Removes files.
+
+
+### sed([options,] search_regex, replacement, file [, file ...])
+### sed([options,] search_regex, replacement, file_array)
+
+Available options:
+
++ `-i`: Replace contents of `file` in-place. _Note that no backups will be created!_
+
+Examples:
+
+```javascript
+sed('-i', 'PROGRAM_VERSION', 'v0.1.3', 'source.js');
+sed(/.*DELETE_THIS_LINE.*\n/, '', 'source.js');
+```
+
+Reads an input string from `file`s, and performs a JavaScript `replace()` on the input
+using the given `search_regex` and `replacement` string or function. Returns the new string after replacement.
+
+Note:
+
+Like unix `sed`, ShellJS `sed` supports capture groups. Capture groups are specified
+using the `$n` syntax:
+
+```javascript
+sed(/(\w+)\s(\w+)/, '$2, $1', 'file.txt');
+```
+
+
+### set(options)
+
+Available options:
+
++ `+/-e`: exit upon error (`config.fatal`)
++ `+/-v`: verbose: show all commands (`config.verbose`)
++ `+/-f`: disable filename expansion (globbing)
+
+Examples:
+
+```javascript
+set('-e'); // exit upon first error
+set('+e'); // this undoes a "set('-e')"
+```
+
+Sets global configuration variables.
+
+
+### sort([options,] file [, file ...])
+### sort([options,] file_array)
+
+Available options:
+
++ `-r`: Reverse the results
++ `-n`: Compare according to numerical value
+
+Examples:
+
+```javascript
+sort('foo.txt', 'bar.txt');
+sort('-r', 'foo.txt');
+```
+
+Return the contents of the `file`s, sorted line-by-line. Sorting multiple
+files mixes their content (just as unix `sort` does).
+
+
+### tail([{'-n': \<num\>},] file [, file ...])
+### tail([{'-n': \<num\>},] file_array)
+
+Available options:
+
++ `-n <num>`: Show the last `<num>` lines of `file`s
+
+Examples:
+
+```javascript
+var str = tail({'-n': 1}, 'file*.txt');
+var str = tail('file1', 'file2');
+var str = tail(['file1', 'file2']); // same as above
+```
+
+Read the end of a `file`.
+
+
+### tempdir()
+
+Examples:
+
+```javascript
+var tmp = tempdir(); // "/tmp" for most *nix platforms
+```
+
+Searches and returns string containing a writeable, platform-dependent temporary directory.
+Follows Python's [tempfile algorithm](http://docs.python.org/library/tempfile.html#tempfile.tempdir).
+
+
+### test(expression)
+
+Available expression primaries:
+
++ `'-b', 'path'`: true if path is a block device
++ `'-c', 'path'`: true if path is a character device
++ `'-d', 'path'`: true if path is a directory
++ `'-e', 'path'`: true if path exists
++ `'-f', 'path'`: true if path is a regular file
++ `'-L', 'path'`: true if path is a symbolic link
++ `'-p', 'path'`: true if path is a pipe (FIFO)
++ `'-S', 'path'`: true if path is a socket
+
+Examples:
+
+```javascript
+if (test('-d', path)) { /* do something with dir */ };
+if (!test('-f', path)) continue; // skip if it's a regular file
+```
+
+Evaluates `expression` using the available primaries and returns corresponding value.
+
+
+### ShellString.prototype.to(file)
+
+Examples:
+
+```javascript
+cat('input.txt').to('output.txt');
+```
+
+Analogous to the redirection operator `>` in Unix, but works with
+`ShellStrings` (such as those returned by `cat`, `grep`, etc.). _Like Unix
+redirections, `to()` will overwrite any existing file!_
+
+
+### ShellString.prototype.toEnd(file)
+
+Examples:
+
+```javascript
+cat('input.txt').toEnd('output.txt');
+```
+
+Analogous to the redirect-and-append operator `>>` in Unix, but works with
+`ShellStrings` (such as those returned by `cat`, `grep`, etc.).
+
+
+### touch([options,] file [, file ...])
+### touch([options,] file_array)
+
+Available options:
+
++ `-a`: Change only the access time
++ `-c`: Do not create any files
++ `-m`: Change only the modification time
++ `-d DATE`: Parse `DATE` and use it instead of current time
++ `-r FILE`: Use `FILE`'s times instead of current time
+
+Examples:
+
+```javascript
+touch('source.js');
+touch('-c', '/path/to/some/dir/source.js');
+touch({ '-r': FILE }, '/path/to/some/dir/source.js');
+```
+
+Update the access and modification times of each `FILE` to the current time.
+A `FILE` argument that does not exist is created empty, unless `-c` is supplied.
+This is a partial implementation of [`touch(1)`](http://linux.die.net/man/1/touch).
+
+
+### uniq([options,] [input, [output]])
+
+Available options:
+
++ `-i`: Ignore case while comparing
++ `-c`: Prefix lines by the number of occurrences
++ `-d`: Only print duplicate lines, one for each group of identical lines
+
+Examples:
+
+```javascript
+uniq('foo.txt');
+uniq('-i', 'foo.txt');
+uniq('-cd', 'foo.txt', 'bar.txt');
+```
+
+Filter adjacent matching lines from `input`.
+
+
+### which(command)
+
+Examples:
+
+```javascript
+var nodeExec = which('node');
+```
+
+Searches for `command` in the system's `PATH`. On Windows, this uses the
+`PATHEXT` variable to append the extension if it's not already executable.
+Returns string containing the absolute path to `command`.
+
+
+### exit(code)
+
+Exits the current process with the given exit `code`.
+
+### error()
+
+Tests if error occurred in the last command. Returns a truthy value if an
+error returned, or a falsy value otherwise.
+
+**Note**: do not rely on the
+return value to be an error message. If you need the last error message, use
+the `.stderr` attribute from the last command's return value instead.
+
+
+### ShellString(str)
+
+Examples:
+
+```javascript
+var foo = ShellString('hello world');
+```
+
+Turns a regular string into a string-like object similar to what each
+command returns. This has special methods, like `.to()` and `.toEnd()`.
+
+
+### env['VAR_NAME']
+
+Object containing environment variables (both getter and setter). Shortcut
+to `process.env`.
+
+### Pipes
+
+Examples:
+
+```javascript
+grep('foo', 'file1.txt', 'file2.txt').sed(/o/g, 'a').to('output.txt');
+echo('files with o\'s in the name:\n' + ls().grep('o'));
+cat('test.js').exec('node'); // pipe to exec() call
+```
+
+Commands can send their output to another command in a pipe-like fashion.
+`sed`, `grep`, `cat`, `exec`, `to`, and `toEnd` can appear on the right-hand
+side of a pipe. Pipes can be chained.
+
+## Configuration
+
+
+### config.silent
+
+Example:
+
+```javascript
+var sh = require('shelljs');
+var silentState = sh.config.silent; // save old silent state
+sh.config.silent = true;
+/* ... */
+sh.config.silent = silentState; // restore old silent state
+```
+
+Suppresses all command output if `true`, except for `echo()` calls.
+Default is `false`.
+
+### config.fatal
+
+Example:
+
+```javascript
+require('shelljs/global');
+config.fatal = true; // or set('-e');
+cp('this_file_does_not_exist', '/dev/null'); // throws Error here
+/* more commands... */
+```
+
+If `true`, the script will throw a Javascript error when any shell.js
+command encounters an error. Default is `false`. This is analogous to
+Bash's `set -e`.
+
+### config.verbose
+
+Example:
+
+```javascript
+config.verbose = true; // or set('-v');
+cd('dir/');
+rm('-rf', 'foo.txt', 'bar.txt');
+exec('echo hello');
+```
+
+Will print each command as follows:
+
+```
+cd dir/
+rm -rf foo.txt bar.txt
+exec echo hello
+```
+
+### config.globOptions
+
+Example:
+
+```javascript
+config.globOptions = {nodir: true};
+```
+
+Use this value for calls to `glob.sync()` instead of the default options.
+
+### config.reset()
+
+Example:
+
+```javascript
+var shell = require('shelljs');
+// Make changes to shell.config, and do stuff...
+/* ... */
+shell.config.reset(); // reset to original state
+// Do more stuff, but with original settings
+/* ... */
+```
+
+Reset `shell.config` to the defaults:
+
+```javascript
+{
+  fatal: false,
+  globOptions: {},
+  maxdepth: 255,
+  noglob: false,
+  silent: false,
+  verbose: false,
+}
+```

+//
+
+var common = require('./src/common');
+
+//@
+//@ All commands run synchronously, unless otherwise stated.
+//@ All commands accept standard bash globbing characters (`*`, `?`, etc.),
+//@ compatible with the [node `glob` module](https://github.com/isaacs/node-glob).
+//@
+//@ For less-commonly used commands and features, please check out our [wiki
+//@ page](https://github.com/shelljs/shelljs/wiki).
+//@
+
+// Include the docs for all the default commands
+//@commands
+
+// Load all default commands
+require('./commands').forEach(function (command) {
+  require('./src/' + command);
+});
+
+//@
+//@ ### exit(code)
+//@
+//@ Exits the current process with the given exit `code`.
+exports.exit = process.exit;
+
+//@include ./src/error
+exports.error = require('./src/error');
+
+//@include ./src/common
+exports.ShellString = common.ShellString;
+
+//@
+//@ ### env['VAR_NAME']
+//@
+//@ Object containing environment variables (both getter and setter). Shortcut
+//@ to `process.env`.
+exports.env = process.env;
+
+//@
+//@ ### Pipes
+//@
+//@ Examples:
+//@
+//@ ```javascript
+//@ grep('foo', 'file1.txt', 'file2.txt').sed(/o/g, 'a').to('output.txt');
+//@ echo('files with o\'s in the name:\n' + ls().grep('o'));
+//@ cat('test.js').exec('node'); // pipe to exec() call
+//@ ```
+//@
+//@ Commands can send their output to another command in a pipe-like fashion.
+//@ `sed`, `grep`, `cat`, `exec`, `to`, and `toEnd` can appear on the right-hand
+//@ side of a pipe. Pipes can be chained.
+
+//@
+//@ ## Configuration
+//@
+
+exports.config = common.config;
+
+//@
+//@ ### config.silent
+//@
+//@ Example:
+//@
+//@ ```javascript
+//@ var sh = require('shelljs');
+//@ var silentState = sh.config.silent; // save old silent state
+//@ sh.config.silent = true;
+//@ /* ... */
+//@ sh.config.silent = silentState; // restore old silent state
+//@ ```
+//@
+//@ Suppresses all command output if `true`, except for `echo()` calls.
+//@ Default is `false`.
+
+//@
+//@ ### config.fatal
+//@
+//@ Example:
+//@
+//@ ```javascript
+//@ require('shelljs/global');
+//@ config.fatal = true; // or set('-e');
+//@ cp('this_file_does_not_exist', '/dev/null'); // throws Error here
+//@ /* more commands... */
+//@ ```
+//@
+//@ If `true`, the script will throw a Javascript error when any shell.js
+//@ command encounters an error. Default is `false`. This is analogous to
+//@ Bash's `set -e`.
+
+//@
+//@ ### config.verbose
+//@
+//@ Example:
+//@
+//@ ```javascript
+//@ config.verbose = true; // or set('-v');
+//@ cd('dir/');
+//@ rm('-rf', 'foo.txt', 'bar.txt');
+//@ exec('echo hello');
+//@ ```
+//@
+//@ Will print each command as follows:
+//@
+//@ ```
+//@ cd dir/
+//@ rm -rf foo.txt bar.txt
+//@ exec echo hello
+//@ ```
+
+//@
+//@ ### config.globOptions
+//@
+//@ Example:
+//@
+//@ ```javascript
+//@ config.globOptions = {nodir: true};
+//@ ```
+//@
+//@ Use this value for calls to `glob.sync()` instead of the default options.
+
+//@
+//@ ### config.reset()
+//@
+//@ Example:
+//@
+//@ ```javascript
+//@ var shell = require('shelljs');
+//@ // Make changes to shell.config, and do stuff...
+//@ /* ... */
+//@ shell.config.reset(); // reset to original state
+//@ // Do more stuff, but with original settings
+//@ /* ... */
+//@ ```
+//@
+//@ Reset `shell.config` to the defaults:
+//@
+//@ ```javascript
+//@ {
+//@   fatal: false,
+//@   globOptions: {},
+//@   maxdepth: 255,
+//@   noglob: false,
+//@   silent: false,
+//@   verbose: false,
+//@ }
+//@ ```
