+
+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.

-unique-filename
-===============
-
-Generate a unique filename for use in temporary directories or caches.
-
-```
-var uniqueFilename = require('unique-filename')
-
-// returns something like: /tmp/912ec803b2ce49e4a541068d495ab570
-var randomTmpfile = uniqueFilename(os.tmpdir())
-
-// returns something like: /tmp/my-test-912ec803b2ce49e4a541068d495ab570
-var randomPrefixedTmpfile = uniqueFilename(os.tmpdir(), 'my-test')
-
-var uniqueTmpfile = uniqueFilename('/tmp', 'testing', '/my/thing/to/uniq/on')
-```
-
-### uniqueFilename(*dir*, *fileprefix*, *uniqstr*) → String
-
-Returns the full path of a unique filename that looks like:
-`dir/prefix-7ddd44c0`
-or `dir/7ddd44c0`
-
-*dir* – The path you want the filename in. `os.tmpdir()` is a good choice for this.
-
-*fileprefix* – A string to append prior to the unique part of the filename.
-The parameter is required if *uniqstr* is also passed in but is otherwise
-optional and can be `undefined`/`null`/`''`. If present and not empty
-then this string plus a hyphen are prepended to the unique part.
-
-*uniqstr* – Optional, if not passed the unique part of the resulting
-filename will be random.  If passed in it will be generated from this string
-in a reproducable way.

+# copy-concurrently
+
+Copy files, directories and symlinks
+
+```
+const copy = require('copy-concurrently')
+copy('/path/to/thing', '/new/path/thing').then(() => {
+  // this is now copied
+}).catch(err => {
+  // oh noooo
+})
+```
+
+Copies files, directories and symlinks.  Ownership is maintained when
+running as root, permissions are always maintained.  On Windows, if symlinks
+are unavailable then junctions will be used.
+
+## PUBLIC INTERFACE
+
+### copy(from, to, [options]) → Promise
+
+Recursively copies `from` to `to` and resolves its promise when finished.
+If `to` already exists then the promise will be rejected with an `EEXIST`
+error.
+
+Options are:
+
+* maxConcurrency – (Default: `1`) The maximum number of concurrent copies to do at once.
+* recurseWith - (Default: `copy.item`) The function to call on each file after recursing into a directory.
+* isWindows - (Default: `process.platform === 'win32'`) If true enables Windows symlink semantics. This requires
+  an extra `stat` to determine if the destination of a symlink is a file or directory. If symlinking a directory
+  fails then we'll try making a junction instead.
+
+Options can also include dependency injection:
+
+* Promise - (Default: `global.Promise`) The promise implementation to use, defaults to Node's.
+* fs - (Default: `require('fs')`) The filesystem module to use.  Can be used
+  to use `graceful-fs` or to inject a mock.
+* writeStreamAtomic - (Default: `require('fs-write-stream-atomic')`) The
+  implementation of `writeStreamAtomic` to use.  Used to inject a mock.
+* getuid - (Default: `process.getuid`) A function that returns the current UID. Used to inject a mock.
+
+## EXTENSION INTERFACE
+
+Ordinarily you'd only call `copy` above.  But it's possible to use it's
+component functions directly.  This is useful if, say, you're writing
+[move-concurently](https://npmjs.com/package/move-concurrently).
+
+### copy.file(from, to, options) → Promise
+
+Copies a ordinary file `from` to destination `to`.  Uses
+`fs-write-stream-atomic` to ensure that the file is entirely copied or not
+at all.
+
+Options are:
+
+* uid, gid - (Optional) If `getuid()` is `0` then this and gid will be used to
+  set the user and group of `to`.  If uid is present then gid must be too.
+* mode - (Optional) If set then `to` will have its perms set to `mode`.
+* fs - (Default: `require('fs')`) The filesystem module to use.  Can be used
+  to use `graceful-fs` or to inject a mock.
+* Promise - (Default: `global.Promise`) The promise implementation to use, defaults to Node's.
+* writeStreamAtomic - (Default `require('fs-write-stream-atomic')`) The
+  implementation of `writeStreamAtomic` to use.  Used to inject a mock.
+
+### copy.symlink(from, to, options) → Promise
+
+Copies a symlink `from` to destination `to`.  If on Windows then if
+symlinking fails, a junction will be used instead.
+
+Options are:
+
+* top - The top level the copy is being run from.  This is used to determine
+  if the symlink destination is within the set of files we're copying or
+  outside it.
+* fs - (Default: `require('fs')`) The filesystem module to use.  Can be used
+  to use `graceful-fs` or to inject a mock.
+* Promise - (Default: `global.Promise`) The promise implementation to use, defaults to Node's.
+* isWindows - (Default: `process.platform === 'win32'`) If true enables Windows symlink semantics. This requires
+  an extra `stat` to determine if the destination of a symlink is a file or directory. If symlinking a directory
+  fails then we'll try making a junction instead.
+
+### copy.recurse(from, to, options) → Promise
+
+Reads all of the files in directory `from` and adds them to the `queue`
+using `recurseWith` (by default `copy.item`).
+
+Options are:
+
+* queue - A [`run-queue`](https://npmjs.com/package/run-queue) object to add files found inside `from` to.
+* recurseWith - (Default: `copy.item`) The function to call on each file after recursing into a directory.
+* uid, gid - (Optional) If `getuid()` is `0` then this and gid will be used to
+  set the user and group of `to`.  If uid is present then gid must be too.
+* mode - (Optional) If set then `to` will have its perms set to `mode`.
+* fs - (Default: `require('fs')`) The filesystem module to use.  Can be used
+  to use `graceful-fs` or to inject a mock.
+* getuid - (Default: `process.getuid`) A function that returns the current UID. Used to inject a mock.
+
+### copy.item(from, to, options) → Promise
+
+Copies some kind of `from` to destination `to`.  This looks at the filetype
+and calls `copy.file`, `copy.symlink` or `copy.recurse` as appropriate.
+
+Symlink copies are queued with a priority such that they happen after all
+file and directory copies as you can't create a junction on windows to a
+file that doesn't exist yet.
+
+Options are:
+
+* top - The top level the copy is being run from.  This is used to determine
+  if the symlink destination is within the set of files we're copying or
+  outside it.
+* queue - The [`run-queue`](https://npmjs.com/package/run-queue) object to
+  pass to `copy.recurse` if `from` is a directory.
+* recurseWith - (Default: `copy.item`) The function to call on each file after recursing into a directory.
+* uid, gid - (Optional) If `getuid()` is `0` then this and gid will be used to
+  set the user and group of `to`.  If uid is present then gid must be too.
+* mode - (Optional) If set then `to` will have its perms set to `mode`.
+* fs - (Default: `require('fs')`) The filesystem module to use.  Can be used
+  to use `graceful-fs` or to inject a mock.
+* getuid - (Default: `process.getuid`) A function that returns the current UID. Used to inject a mock.
+* isWindows - (Default: `process.platform === 'win32'`) If true enables Windows symlink semantics. This requires
+  an extra `stat` to determine if the destination of a symlink is a file or directory. If symlinking a directory
+  fails then we'll try making a junction instead.
+* Promise - (Default: `global.Promise`) The promise implementation to use, defaults to Node's.
+* writeStreamAtomic - (Default `require('fs-write-stream-atomic')`) The
+  implementation of `writeStreamAtomic` to use.  Used to inject a mock.

+
+Define multiple non-enumerable properties at once. Uses `Object.defineProperty` when available; falls back to standard assignment in older engines.
+Existing properties are not overridden. Accepts a map of property names to a predicate that, when true, force-overrides.
+
+## Example
+
+```js
+var define = require('define-properties');
+var assert = require('assert');
+
+var obj = define({ a: 1, b: 2 }, {
+	a: 10,
+	b: 20,
+	c: 30
+});
+assert(obj.a === 1);
+assert(obj.b === 2);
+assert(obj.c === 30);
+if (define.supportsDescriptors) {
+	assert.deepEqual(Object.keys(obj), ['a', 'b']);
+	assert.deepEqual(Object.getOwnPropertyDescriptor(obj, 'c'), {
+		configurable: true,
+		enumerable: false,
+		value: 30,
+		writable: false
+	});
+}
+```
+
+Then, with predicates:
+```js
+var define = require('define-properties');
+var assert = require('assert');
+
+var obj = define({ a: 1, b: 2, c: 3 }, {
+	a: 10,
+	b: 20,
+	c: 30
+}, {
+	a: function () { return false; },
+	b: function () { return true; }
+});
+assert(obj.a === 1);
+assert(obj.b === 20);
+assert(obj.c === 3);
+if (define.supportsDescriptors) {
+	assert.deepEqual(Object.keys(obj), ['a', 'c']);
+	assert.deepEqual(Object.getOwnPropertyDescriptor(obj, 'b'), {
+		configurable: true,
+		enumerable: false,
+		value: 20,
+		writable: false
+	});
+}
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`

+
+ECMAScript spec abstract operations.
+When different versions of the spec conflict, the default export will be the latest version of the abstract operation.
+All abstract operations will also be available under an `es5`/`es2015`/`es2016` entry point, and exported property, if you require a specific version.
+
+## Example
+
+```js
+var ES = require('es-abstract');
+var assert = require('assert');
+
+assert(ES.isCallable(function () {}));
+assert(!ES.isCallable(/a/g));
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`

+
+ECMAScript “ToPrimitive” algorithm. Provides ES5 and ES2015 versions.
+When different versions of the spec conflict, the default export will be the latest version of the abstract operation.
+Alternative versions will also be available under an `es5`/`es2015` exported property if you require a specific version.
+
+## Example
+
+```js
+var toPrimitive = require('es-to-primitive');
+var assert = require('assert');
+
+assert(toPrimitive(function () {}) === String(function () {}));
+
+var date = new Date();
+assert(toPrimitive(date) === String(date));
+
+assert(toPrimitive({ valueOf: function () { return 3; } }) === 3);
+
+assert(toPrimitive(['a', 'b', 3]) === String(['a', 'b', 3]));
+
+var sym = Symbol();
+assert(toPrimitive(Object(sym)) === sym);
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`

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

+Determine if the JS environment has Symbol support. Supports spec, or shams.
+
+## Example
+
+```js
+var hasSymbols = require('has-symbols');
+
+hasSymbols() === true; // if the environment has native Symbol support. Not polyfillable, not forgeable.
+
+var hasSymbolsKinda = require('has-symbols/shams');
+hasSymbolsKinda() === true; // if the environment has a Symbol sham that mostly follows the spec.
+```
+
+## Supported Symbol shams
+ - get-own-property-symbols [npm](https://www.npmjs.com/package/get-own-property-symbols) | [github](https://github.com/WebReflection/get-own-property-symbols)
+ - core-js [npm](https://www.npmjs.com/package/core-js) | [github](https://github.com/zloirock/core-js)
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`

+
+assert.notOk(isCallable(undefined));
+assert.notOk(isCallable(null));
+assert.notOk(isCallable(false));

+assert.notOk(isCallable(new Date()));
+assert.notOk(isCallable(42));
+assert.notOk(isCallable(NaN));
+assert.notOk(isCallable(Infinity));
+assert.notOk(isCallable(new Number(42)));
+assert.notOk(isCallable('foo'));
+assert.notOk(isCallable(Object('foo')));
+
+assert.ok(isCallable(function () {}));
+assert.ok(isCallable(function* () {}));
+assert.ok(isCallable(x => x * x));
+```
+
+## Tests

+1.0.4 / 2016-02-18
+=================
+  * [Fix] ensure that `lastIndex` is not mutated (#3)
+  * [Refactor] when try/catch is needed, bail early if the value lacks an own `lastIndex` data property
+  * [Refactor] use an early return instead of a ternary
+  * [Refactor] bail earlier when the value is falsy
+  * Switch from vb.teelaun.ch to versionbadg.es for the npm version badge SVG
+  * [Dev Deps] update `tape`, `jscs`, `editorconfig-tools`, `eslint`, `semver`, `replace`, `nsp`, `covert`, `@ljharb/eslint-config`
+  * [Tests] on all the node and io.js versions; improve test matri
+  * [Tests] Fix tests for faked @@toStringTag
+
+1.0.3 / 2015-01-29
+=================
+  * If @@toStringTag is not present, use the old-school Object#toString test.
+
+1.0.2 / 2015-01-29
+=================
+  * Improve optimization by separating the try/catch, and bailing out early when not typeof "object".
+
+1.0.1 / 2015-01-28
+=================
+  * Update `jscs`, `tape`, `covert`
+  * Use RegExp#exec to test if something is a regex, which works even with ES6 @@toStringTag.
+
+1.0.0 / 2014-05-19
+=================
+  * Initial release.

+Is this value a JS regex?
+This module works cross-realm/iframe, and despite ES6 @@toStringTag.
+
+## Example
+
+```js
+var isRegex = require('is-regex');
+var assert = require('assert');
+
+assert.notOk(isRegex(undefined));
+assert.notOk(isRegex(null));
+assert.notOk(isRegex(false));
+assert.notOk(isRegex(true));
+assert.notOk(isRegex(42));
+assert.notOk(isRegex('foo'));
+assert.notOk(isRegex(function () {}));
+assert.notOk(isRegex([]));
+assert.notOk(isRegex({}));
+
+assert.ok(isRegex(/a/g));
+assert.ok(isRegex(new RegExp('a', 'g')));
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`

+
+```js
+var isSymbol = require('is-symbol');
+assert(!isSymbol(function () {}));
+assert(!isSymbol(null));
+assert(!isSymbol(function* () { yield 42; return Infinity; });
+
+assert(isSymbol(Symbol.iterator));
+assert(isSymbol(Symbol('foo')));
+assert(isSymbol(Symbol.for('foo')));

+# move-concurrently
+
+Move files and directories.
+
+```
+const move = require('move-concurrently')
+move('/path/to/thing', '/new/path/thing'), err => {
+  if (err) throw err
+  // thing is now moved!
+})
+```
+
+Uses `rename` to move things as fast as possible.
+
+If you `move` across devices or on filesystems that don't support renaming
+large directories.  That is, situations that result in `rename` returning
+the `EXDEV` error, then `move` will fallback to copy + delete.
+
+When recursively copying directories it will first try to rename the
+contents before falling back to copying.  While this will be slightly slower
+in true cross-device scenarios, it is MUCH faster in cases where the
+filesystem can't handle directory renames.
+
+When copying ownership is maintained when running as root.  Permissions are
+always maintained.  On Windows, if symlinks are unavailable then junctions
+will be used.
+
+## INTERFACE
+
+### move(from, to, options) → Promise
+
+Recursively moves `from` to `to` and resolves its promise when finished.
+If `to` already exists then the promise will be rejected with an `EEXIST`
+error.
+
+Starts by trying to rename `from` to `to`.
+
+Options are:
+
+* maxConcurrency – (Default: `1`) The maximum number of concurrent copies to do at once.
+* isWindows - (Default: `process.platform === 'win32'`) If true enables Windows symlink semantics. This requires
+  an extra `stat` to determine if the destination of a symlink is a file or directory. If symlinking a directory
+  fails then we'll try making a junction instead.
+
+Options can also include dependency injection:
+
+* Promise - (Default: `global.Promise`) The promise implementation to use, defaults to Node's.
+* fs - (Default: `require('fs')`) The filesystem module to use.  Can be used
+  to use `graceful-fs` or to inject a mock.
+* writeStreamAtomic - (Default: `require('fs-write-stream-atomic')`) The
+  implementation of `writeStreamAtomic` to use.  Used to inject a mock.
+* getuid - (Default: `process.getuid`) A function that returns the current UID. Used to inject a mock.

+
+An Object.keys shim. Invoke its "shim" method to shim Object.keys if it is unavailable.
+
+Most common usage:
+```js
+var keys = Object.keys || require('object-keys');
+```
+
+## Example
+
+```js
+var keys = require('object-keys');
+var assert = require('assert');
+var obj = {
+	a: true,
+	b: true,
+	c: true
+};
+
+assert.deepEqual(keys(obj), ['a', 'b', 'c']);
+```
+
+```js
+var keys = require('object-keys');
+var assert = require('assert');
+/* when Object.keys is not present */
+delete Object.keys;
+var shimmedKeys = keys.shim();
+assert.equal(shimmedKeys, keys);
+assert.deepEqual(Object.keys(obj), keys(obj));
+```
+
+```js
+var keys = require('object-keys');
+var assert = require('assert');
+/* when Object.keys is present */
+var shimmedKeys = keys.shim();
+assert.equal(shimmedKeys, Object.keys);
+assert.deepEqual(Object.keys(obj), keys(obj));
+```
+

+
+An ES2017 spec-compliant shim for `Object.getOwnPropertyDescriptors` that works in ES5.
+Invoke its "shim" method to shim `Object.getOwnPropertyDescriptors` if it is unavailable, and if `Object.getOwnPropertyDescriptor` is available.
+
+This package implements the [es-shim API](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the [spec](https://github.com/tc39/ecma262/pull/582).
+
+## Example
+
+```js
+var getDescriptors = require('object.getownpropertydescriptors');
+var assert = require('assert');
+var obj = { normal: Infinity };
+var enumDescriptor = {
+	enumerable: false,
+	writable: false,
+	configurable: true,
+	value: true
+};
+var writableDescriptor = {
+	enumerable: true,
+	writable: true,
+	configurable: true,
+	value: 42
+};
+var symbol = Symbol();
+var symDescriptor = {
+	enumerable: true,
+	writable: true,
+	configurable: false,
+	value: [symbol]
+};
+
+Object.defineProperty(obj, 'enumerable', enumDescriptor);
+Object.defineProperty(obj, 'writable', writableDescriptor);
+Object.defineProperty(obj, 'symbol', symDescriptor);
+
+var descriptors = getDescriptors(obj);
+
+assert.deepEqual(descriptors, {
+	normal: {
+		enumerable: true,
+		writable: true,
+		configurable: true,
+		value: Infinity
+	},
+	enumerable: enumDescriptor,
+	writable: writableDescriptor,
+	symbol: symDescriptor
+});
+```
+
+```js
+var getDescriptors = require('object.getownpropertydescriptors');
+var assert = require('assert');
+/* when Object.getOwnPropertyDescriptors is not present */
+delete Object.getOwnPropertyDescriptors;
+var shimmedDescriptors = getDescriptors.shim();
+assert.equal(shimmedDescriptors, getDescriptors);
+assert.deepEqual(shimmedDescriptors(obj), getDescriptors(obj));
+```
+
+```js
+var getDescriptors = require('object.getownpropertydescriptors');
+var assert = require('assert');
+/* when Object.getOwnPropertyDescriptors is present */
+var shimmedDescriptors = getDescriptors.shim();
+assert.notEqual(shimmedDescriptors, getDescriptors);
+assert.deepEqual(shimmedDescriptors(obj), getDescriptors(obj));
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`

 Parse a query string into an object. Leading `?` or `#` are ignored, so you can pass `location.search` or `location.hash` directly.
 
 The returned object is created with [`Object.create(null)`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/create) and thus does not have a `prototype`.

-- `bracket`: stands for parsing correctly arrays with bracket representation on the query string, such as:
+```js
+queryString.stringify({foo: [1, 2, 3]}, {arrayFormat: 'bracket'});
+//=> 'foo[]=1&foo[]=2&foo[]=3'
+```
+
+- `index`: Serialize arrays using index representation:
 
 ```js
-queryString.stringify({foo: [1,2,3]}, {arrayFormat: 'bracket'});
-// => foo[]=1&foo[]=2&foo[]=3
+queryString.stringify({foo: [1, 2, 3]}, {arrayFormat: 'index'});
+//=> 'foo[0]=1&foo[1]=2&foo[3]=3'
 ```
 
-- `index`: stands for parsing taking the index into account, such as:
+- `comma`: Serialize arrays by separating elements with comma:
 
 ```js
-queryString.stringify({foo: [1,2,3]}, {arrayFormat: 'index'});
-// => foo[0]=1&foo[1]=2&foo[3]=3
+queryString.stringify({foo: [1, 2, 3]}, {arrayFormat: 'comma'});
+//=> 'foo=1,2,3'
 ```
 
-- `none`: is the __default__ option and removes any bracket representation, such as:
+- `none`: Serialize arrays by using duplicate keys:
 
 ```js
-queryString.stringify({foo: [1,2,3]});
-// => foo=1&foo=2&foo=3
+queryString.stringify({foo: [1, 2, 3]});
+//=> 'foo=1&foo=2&foo=3'
 ```
 
-#### sort
+##### sort
 
-Type: `Function` `boolean`
+Type: `Function | boolean`
 
 Supports both `Function` as a custom sorting function or `false` to disable sorting.
 
 ```js
 const order = ['c', 'a', 'b'];
-queryString.stringify({ a: 1, b: 2, c: 3}, {
-	sort: (m, n) => order.indexOf(m) >= order.indexOf(n)
+
+queryString.stringify({a: 1, b: 2, c: 3}, {
+	sort: (a, b) => order.indexOf(a) - order.indexOf(b)
 });
-// => 'c=3&a=1&b=2'
+//=> 'c=3&a=1&b=2'
 ```
 
 ```js
-queryString.stringify({ b: 1, c: 2, a: 3}, {sort: false});
-// => 'c=3&a=1&b=2'
+queryString.stringify({b: 1, c: 2, a: 3}, {sort: false});
+//=> 'b=1&c=2&a=3'
 ```
 
-If omitted, keys are sorted using `Array#sort`, which means, converting them to strings and comparing strings in Unicode code point order.
+If omitted, keys are sorted using `Array#sort()`, which means, converting them to strings and comparing strings in Unicode code point order.
 
-### .extract(*string*)
+### .extract(string)
 
 Extract a query string from a URL that can be passed into `.parse()`.
 
-### .parseUrl(*string*, *[options]*)
+### .parseUrl(string, [options])
 
 Extract the URL and the query string as an object.

 If you want to guarantee a stable streams base, regardless of what version of
 Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).

-### Streams Working Group
-
-The Node.js Streams is jointly governed by a Working Group
-(WG)
-that is responsible for high-level guidance of the project.
-
-The WG has final authority over this project including:
-
-* Technical direction
-* Project governance and process (including this policy)
-* Contribution policy
-* GitHub repository hosting
-* Conduct guidelines
-* Maintaining the list of additional Collaborators
-
-For the current list of WG members, see the project
-[README.md](./README.md#current-project-team-members).
-
-### Collaborators
-
-The readable-stream GitHub repository is
-maintained by the WG and additional Collaborators who are added by the
-WG on an ongoing basis.
-
-Individuals making significant and valuable contributions are made
-Collaborators and given commit-access to the project. These
-individuals are identified by the WG and their addition as
-Collaborators is discussed during the WG meeting.
-
-_Note:_ If you make a significant contribution and are not considered
-for commit-access log an issue or contact a WG member directly and it
-will be brought up in the next WG meeting.
-
-Modifications of the contents of the readable-stream repository are
-made on
-a collaborative basis. Anybody with a GitHub account may propose a
-modification via pull request and it will be considered by the project
-Collaborators. All pull requests must be reviewed and accepted by a
-Collaborator with sufficient expertise who is able to take full
-responsibility for the change. In the case of pull requests proposed
-by an existing Collaborator, an additional Collaborator is required
-for sign-off. Consensus should be sought if additional Collaborators
-participate and there is disagreement around a particular
-modification. See _Consensus Seeking Process_ below for further detail
-on the consensus model used for governance.
-
-Collaborators may opt to elevate significant or controversial
-modifications, or modifications that have not found consensus to the
-WG for discussion by assigning the ***WG-agenda*** tag to a pull
-request or issue. The WG should serve as the final arbiter where
-required.
-
-For the current list of Collaborators, see the project
-[README.md](./README.md#members).
-
-### WG Membership
-
-WG seats are not time-limited.  There is no fixed size of the WG.
-However, the expected target is between 6 and 12, to ensure adequate
-coverage of important areas of expertise, balanced with the ability to
-make decisions efficiently.
-
-There is no specific set of requirements or qualifications for WG
-membership beyond these rules.
-
-The WG may add additional members to the WG by unanimous consensus.
-
-A WG member may be removed from the WG by voluntary resignation, or by
-unanimous consensus of all other WG members.
-
-Changes to WG membership should be posted in the agenda, and may be
-suggested as any other agenda item (see "WG Meetings" below).
-
-If an addition or removal is proposed during a meeting, and the full
-WG is not in attendance to participate, then the addition or removal
-is added to the agenda for the subsequent meeting.  This is to ensure
-that all members are given the opportunity to participate in all
-membership decisions.  If a WG member is unable to attend a meeting
-where a planned membership decision is being made, then their consent
-is assumed.
-
-No more than 1/3 of the WG members may be affiliated with the same
-employer.  If removal or resignation of a WG member, or a change of
-employment by a WG member, creates a situation where more than 1/3 of
-the WG membership shares an employer, then the situation must be
-immediately remedied by the resignation or removal of one or more WG
-members affiliated with the over-represented employer(s).
-
-### WG Meetings
-
-The WG meets occasionally on a Google Hangout On Air. A designated moderator
-approved by the WG runs the meeting. Each meeting should be
-published to YouTube.
-
-Items are added to the WG agenda that are considered contentious or
-are modifications of governance, contribution policy, WG membership,
-or release process.
-
-The intention of the agenda is not to approve or review all patches;
-that should happen continuously on GitHub and be handled by the larger
-group of Collaborators.
-
-Any community member or contributor can ask that something be added to
-the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
-WG member or the moderator can add the item to the agenda by adding
-the ***WG-agenda*** tag to the issue.
-
-Prior to each WG meeting the moderator will share the Agenda with
-members of the WG. WG members can add any items they like to the
-agenda at the beginning of each meeting. The moderator and the WG
-cannot veto or remove items.
-
-The WG may invite persons or representatives from certain projects to
-participate in a non-voting capacity.
-
-The moderator is responsible for summarizing the discussion of each
-agenda item and sends it as a pull request after the meeting.
-
-### Consensus Seeking Process
-
-The WG follows a
-[Consensus
-Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
-decision-making model.
-
-When an agenda item has appeared to reach a consensus the moderator
-will ask "Does anyone object?" as a final call for dissent from the
-consensus.
-
-If an agenda item cannot reach a consensus a WG member can call for
-either a closing vote or a vote to table the issue to the next
-meeting. The call for a vote must be seconded by a majority of the WG
-or else the discussion will continue. Simple majority wins.
-
-Note that changes to WG membership require a majority consensus.  See
-"WG Membership" above.

-
-***Node-core streams for userland***
-
-This package is a mirror of the Streams2 and Streams3 implementations in
-Node-core.
-
-Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
-
-If you want to guarantee a stable streams base, regardless of what version of
-Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
-
-As of version 2.0.0 **readable-stream** uses semantic versioning.
-
-# Streams Working Group
-
-`readable-stream` is maintained by the Streams Working Group, which
-oversees the development and maintenance of the Streams API within
-Node.js. The responsibilities of the Streams Working Group include:
-
-* Addressing stream issues on the Node.js issue tracker.
-* Authoring and editing stream documentation within the Node.js project.
-* Reviewing changes to stream subclasses within the Node.js project.
-* Redirecting changes to streams from the Node.js project to this
-  project.
-* Assisting in the implementation of stream providers within Node.js.
-* Recommending versions of `readable-stream` to be included in Node.js.
-* Messaging about the future of streams to give the community advance
-  notice of changes.

-## Agenda
-
-Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
-
-* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
-* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
-* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
-* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
-
-## Minutes
-
-### adopt a charter
-
-* group: +1's all around
-
-### What versioning scheme should be adopted?
-* group: +1’s 3.0.0
-* domenic+group: pulling in patches from other sources where appropriate
-* mikeal: version independently, suggesting versions for io.js
-* mikeal+domenic: work with TC to notify in advance of changes
-simpler stream creation
-
-### streamline creation of streams
-* sam: streamline creation of streams
-* domenic: nice simple solution posted
-  but, we lose the opportunity to change the model
-  may not be backwards incompatible (double check keys)
-
-  **action item:** domenic will check
-
-### remove implicit flowing of streams on(‘data’)
-* add isFlowing / isPaused
-* mikeal: worrying that we’re documenting polyfill methods – confuses users
-* domenic: more reflective API is probably good, with warning labels for users
-* new section for mad scientists (reflective stream access)
-* calvin: name the “third state”
-* mikeal: maybe borrow the name from whatwg?
-* domenic: we’re missing the “third state”
-* consensus: kind of difficult to name the third state
-* mikeal: figure out differences in states / compat
-* mathias: always flow on data – eliminates third state
-  * explore what it breaks
-
-**action items:**
-* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
-* ask rod/build for infrastructure
-* **chris**: explore the “flow on data” approach
-* add isPaused/isFlowing
-* add new docs section
-* move isPaused to that section

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

-
-
-[![NPM](https://nodei.co/npm/string_decoder.png?downloads=true&downloadRank=true)](https://nodei.co/npm/string_decoder/)
-[![NPM](https://nodei.co/npm-dl/string_decoder.png?&months=6&height=3)](https://nodei.co/npm/string_decoder/)
-
-
-```bash
-npm install --save string_decoder
-```
-
-***Node-core string_decoder for userland***
-
-This package is a mirror of the string_decoder implementation in Node-core.
-
-Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
-
-As of version 1.0.0 **string_decoder** uses semantic versioning.
-
-## Previous versions
-
-Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
-
-## Update
-
-The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
-
-## Streams Working Group
-
-`string_decoder` is maintained by the Streams Working Group, which
-oversees the development and maintenance of the Streams API within
-Node.js. The responsibilities of the Streams Working Group include:
-
-* Addressing stream issues on the Node.js issue tracker.
-* Authoring and editing stream documentation within the Node.js project.
-* Reviewing changes to stream subclasses within the Node.js project.
-* Redirecting changes to streams from the Node.js project to this
-  project.
-* Assisting in the implementation of stream providers within Node.js.
-* Recommending versions of `readable-stream` to be included in Node.js.
-* Messaging about the future of streams to give the community advance
-  notice of changes.
-
-See [readable-stream](https://github.com/nodejs/readable-stream) for
-more details.

+     #  A large portion of the dictionary entries

+     #  Free Software applies to the current dictionary as well.
+     #
+     #  Each User may also freely distribute the Program, whether in its
+     #  original form or modified, to any third party or parties, PROVIDED
+     #  that the provisions of Section 3 ("NO WARRANTY") will ALWAYS appear

+     #
+     #  NO WARRANTY

+     #  to users as so produced on an experimental basis.  Accordingly, the

+     #  includes, but is not limited to, any warranty of the quality,

+     #  the program and the nonexistence of any infringement or violation of
+     #  any right of any third party.
+     #
+     #  Each user of the program will agree and understand, and be deemed to
+     #  have agreed and understood, that there is no warranty whatsoever for
+     #  the program and, accordingly, the entire risk arising from or
+     #  otherwise connected with the program is assumed by the user.
+     #
+     #  Therefore, neither ICOT, the copyright holder, or any other

+     #  or result produced or otherwise obtained by using the program,
+     #  regardless of whether they have been advised of, or otherwise had
+     #  knowledge of, the possibility of such damages at any time during the
+     #  project or thereafter.  Each user will be deemed to have agreed to the
+     #  foregoing by his or her commencement of use of the program.  The term
+     #  "use" as used herein includes, but is not limited to, the use,
+     #  modification, copying and distribution of the program and the
+     #  production of secondary products from the program.
+     #
+     #  In the case where the program, whether in its original form or

+    5. Time Zone Database
+
+      ICU uses the public domain data and code derived from Time Zone
+    Database for its time zone support. The ownership of the TZ database
+    is explained in BCP 175: Procedure for Maintaining the Time Zone
+    Database section 7.
+
+     # 7.  Database Ownership
+     #
+     #    The TZ database itself is not an IETF Contribution or an IETF
+     #    document.  Rather it is a pre-existing and regularly updated work
+     #    that is in the public domain, and is intended to remain in the
+     #    public domain.  Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do
+     #    not apply to the TZ Database or contributions that individuals make
+     #    to it.  Should any claims be made and substantiated against the TZ
+     #    Database, the organization that is providing the IANA
+     #    Considerations defined in this RFC, under the memorandum of
+     #    understanding with the IETF, currently ICANN, may act in accordance
+     #    with all competent court orders.  No ownership claims will be made
+     #    by ICANN or the IETF Trust on the database or the code.  Any person
+     #    making a contribution to the database or code waives all rights to
+     #    future claims in that contribution or in the TZ Database.

+    Package available as open source and free software.
+
+    You are always permitted to make arrangements wholly outside of this
+    license directly with the Copyright Holder of a given Package.  If the
+    terms of this license do not permit the full use that you propose to
+    make of the Package, you should contact the Copyright Holder and seek
+    a different licensing arrangement.
+
+    Definitions
+
+        "Copyright Holder" means the individual(s) or organization(s)
+        named in the copyright notice for the entire Package.
+
+        "Contributor" means any party that has contributed code or other
+        material to the Package, in accordance with the Copyright Holder's
+        procedures.
+
+        "You" and "your" means any person who would like to copy,
+        distribute, or modify the Package.
+
+        "Package" means the collection of files distributed by the

+        those files. A given Package may consist of either the Standard
+        Version, or a Modified Version.
+
+        "Distribute" means providing a copy of the Package or making it
+        accessible to anyone else, or in the case of a company or
+        organization, to others outside of your company or organization.

+        "Distributor Fee" means any fee that you charge for Distributing
+        this Package or providing support for this Package to another
+        party.  It does not mean licensing fees.
+
+        "Standard Version" refers to the Package if it has not been
+        modified, or has been modified only in ways explicitly requested
+        by the Copyright Holder.
+
+        "Modified Version" means the Package, if it has been changed, and
+        such changes were not explicitly requested by the Copyright
+        Holder.
+
+        "Original License" means this Artistic License as Distributed with
+        the Standard Version of the Package, in its current version or as
+        it may be modified by The Perl Foundation in the future.
+
+        "Source" form means the source code, documentation source, and
+        configuration files for the Package.
+
+        "Compiled" form means the compiled bytecode, object code, binary,
+        or any other form resulting from mechanical transformation or
+        translation of the Source form.
+
+    Permission for Use and Modification Without Distribution
+
+    (1)  You are permitted to use the Standard Version and create and use
+    Modified Versions for any purpose without restriction, provided that
+    you do not Distribute the Modified Version.
+
+    Permissions for Redistribution of the Standard Version
+
+    (2)  You may Distribute verbatim copies of the Source form of the
+    Standard Version of this Package in any medium without restriction,
+    either gratis or for a Distributor Fee, provided that you duplicate
+    all of the original copyright notices and associated disclaimers.  At
+    your discretion, such verbatim copies may or may not include a
+    Compiled form of the Package.
+
+    (3)  You may apply any bug fixes, portability changes, and other
+    modifications made available from the Copyright Holder.  The resulting
+    Package will still be considered the Standard Version, and as such
+    will be subject to the Original License.
+
+    Distribution of Modified Versions of the Package as Source
+
+    (4)  You may Distribute your Modified Version as Source (either gratis
+    or for a Distributor Fee, and with or without a Compiled form of the
+    Modified Version) provided that you clearly document how it differs
+    from the Standard Version, including, but not limited to, documenting
+    any non-standard features, executables, or modules, and provided that
+    you do at least ONE of the following:
+
+        (a)  make the Modified Version available to the Copyright Holder
+        of the Standard Version, under the Original License, so that the
+        Copyright Holder may include your modifications in the Standard
+        Version.
+
+        (b)  ensure that installation of your Modified Version does not
+        prevent the user installing or running the Standard Version. In
+        addition, the Modified Version must bear a name that is different
+        from the name of the Standard Version.
+
+        (c)  allow anyone who receives a copy of the Modified Version to
+        make the Source form of the Modified Version available to others
+        under
+
+            (i)  the Original License or
+
+            (ii)  a license that permits the licensee to freely copy,
+            modify and redistribute the Modified Version using the same
+            licensing terms that apply to the copy that the licensee
+            received, and requires that the Source form of the Modified
+            Version, and of any works derived from it, be made freely
+            available in that license fees are prohibited but Distributor
+            Fees are allowed.
+
+    Distribution of Compiled Forms of the Standard Version
+    or Modified Versions without the Source
+
+    (5)  You may Distribute Compiled forms of the Standard Version without
+    the Source, provided that you include complete instructions on how to
+    get the Source of the Standard Version.  Such instructions must be
+    valid at the time of your distribution.  If these instructions, at any
+    time while you are carrying out such distribution, become invalid, you
+    must provide new instructions on demand or cease further distribution.
+    If you provide valid instructions or cease distribution within thirty
+    days after you become aware that the instructions are invalid, then
+    you do not forfeit any of your rights under this license.
+
+    (6)  You may Distribute a Modified Version in Compiled form without
+    the Source, provided that you comply with Section 4 with respect to
+    the Source of the Modified Version.
+
+    Aggregating or Linking the Package
+
+    (7)  You may aggregate the Package (either the Standard Version or
+    Modified Version) with other packages and Distribute the resulting
+    aggregation provided that you do not charge a licensing fee for the
+    Package.  Distributor Fees are permitted, and licensing fees for other
+    components in the aggregation are permitted. The terms of this license
+    apply to the use and Distribution of the Standard or Modified Versions
+    as included in the aggregation.
+
+    (8) You are permitted to link Modified and Standard Versions with
+    other works, to embed the Package in a larger work of your own, or to
+    build stand-alone binary or bytecode versions of applications that
+    include the Package, and Distribute the result without restriction,
+    provided the result does not expose a direct interface to the Package.
+
+    Items That are Not Considered Part of a Modified Version
+
+    (9) Works (including, but not limited to, modules and scripts) that
+    merely extend or make use of the Package, do not, by themselves, cause
+    the Package to be a Modified Version.  In addition, such works are not
+    considered parts of the Package itself, and are not subject to the
+    terms of this license.
+
+    General Provisions
+
+    (10)  Any use, modification, and distribution of the Standard or
+    Modified Versions is governed by this Artistic License. By using,
+    modifying or distributing the Package, you accept this license. Do not
+    use, modify, or distribute the Package, if you do not accept this
+    license.
+
+    (11)  If your Modified Version has been derived from a Modified
+    Version made by someone other than you, you are nevertheless required
+    to ensure that your Modified Version complies with the requirements of
+    this license.
+
+    (12)  This license does not grant you the right to use any trademark,
+    service mark, tradename, or logo of the Copyright Holder.
+
+    (13)  This license includes the non-exclusive, worldwide,
+    free-of-charge patent license to make, have made, use, offer to sell,
+    sell, import and otherwise transfer the Package with respect to any
+    patent claims licensable by the Copyright Holder that are necessarily
+    infringed by the Package. If you institute patent litigation
+    (including a cross-claim or counterclaim) against any party alleging
+    that the Package constitutes direct or contributory patent
+    infringement, then this Artistic License to you shall terminate on the
+    date that such litigation is filed.
+
+    (14)  Disclaimer of Warranty:
+    THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS
+    IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR

+    BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
+    DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF
+    ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.
