+## Development
+
+You might want to know that:
+
+- Mocha is one of the _most-depended-upon_ modules on npm (source: [libraries.io](https://libraries.io/search?order=desc&platforms=NPM&sort=dependents_count)), and
+- Mocha is an _independent_ open-source project, maintained exclusively by volunteers.
+
+You might want to help:
+
+- New to contributing to Mocha? Check out this list of [good first issues](https://github.com/mochajs/mocha/issues?q=is%3Aissue+is%3Aopen+label%3Agood-first-issue)
+- Mocha could use a hand with [these issues](https://github.com/mochajs/mocha/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22)
+- The [maintainer's handbook](https://github.com/mochajs/mocha/blob/master/MAINTAINERS.md) explains how things get done
+
+Finally, come [chat with the maintainers](https://gitter.im/mochajs/contributors) on Gitter if you want to help with:
+
+- Triaging issues, answering questions
+- Review, merging, and closing pull requests
+- Other project-maintenance-y things

+# 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.
+
+![a fun cartoon logo made of glob characters](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.
+* `fs` File-system object with Node's `fs` API. By default, the built-in
+  `fs` module will be used. Set to a volume provided by a library like
+  `memfs` to avoid using the "real" file-system.
+
+## 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.

+# minimatch
+
+A minimal matching utility.
+
+[![Build Status](https://travis-ci.org/isaacs/minimatch.svg?branch=master)](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.)
+
+### partial
+
+Compare a partial path to a pattern.  As long as the parts of the path that
+are present are not contradicted by the pattern, it will be treated as a
+match.  This is useful in applications where you're walking through a
+folder structure, and don't yet have the full path, but want to ensure that
+you do not walk down paths that can never be a match.
+
+For example,
+
+```js
+minimatch('/a/b', '/a/*/c/d', { partial: true })  // true, might be /a/b/c/d
+minimatch('/a/b', '/**/d', { partial: true })     // true, might be /a/b/.../d
+minimatch('/x/y/z', '/a/**/z', { partial: true }) // false, because x !== a
+```
+
+### allowWindowsEscape
+
+Windows path separator `\` is by default converted to `/`, which
+prohibits the usage of `\` as a escape character. This flag skips that
+behavior and allows using the escape character.
+
+## 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.

+# minimatch
+
+A minimal matching utility.
+
+[![Build Status](https://travis-ci.org/isaacs/minimatch.svg?branch=master)](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`
+
+## 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 in patterns
+will always be interpreted as escape characters, not path separators.
+
+Note that `\` or `/` _will_ be interpreted as path separators in paths on
+Windows, and will match against `/` in glob expressions.
+
+So just always use `/` in patterns.
+
+## 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.)
+
+### partial
+
+Compare a partial path to a pattern.  As long as the parts of the path that
+are present are not contradicted by the pattern, it will be treated as a
+match.  This is useful in applications where you're walking through a
+folder structure, and don't yet have the full path, but want to ensure that
+you do not walk down paths that can never be a match.
+
+For example,
+
+```js
+minimatch('/a/b', '/a/*/c/d', { partial: true })  // true, might be /a/b/c/d
+minimatch('/a/b', '/**/d', { partial: true })     // true, might be /a/b/.../d
+minimatch('/x/y/z', '/a/**/z', { partial: true }) // false, because x !== a
+```
+
+## 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.
+
+Note that `fnmatch(3)` in libc is an extremely naive string comparison
+matcher, which does not do anything special for slashes.  This library is
+designed to be used in glob searching and file walkers, and so it does do
+special things with `/`.  Thus, `foo*` will not match `foo/bar` in this
+library, even though it would in `fnmatch(3)`.

+
+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.
+
+## Installation
+
+With [npm](https://npmjs.org) do:
+
+```bash
+npm install brace-expansion
+```

+# ms
+
+![CI](https://github.com/vercel/ms/workflows/CI/badge.svg)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+ms('-3 days') // -259200000
+ms('-1h')     // -3600000
+ms('-200')    // -200
+```
+
+### Convert from Milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(-3 * 60000)        // "-3m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time Format Written-Out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(-3 * 60000, { long: true })        // "-3 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [Node.js](https://nodejs.org) and in the browser
+- If a number is supplied to `ms`, a string with a unit is returned
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
+- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
+
+## Related Packages
+
+- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
+
+## Caught a Bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`
