+
+> [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+<img src="screenshot.svg" width="900">
+
+## Install
+
+```
+$ npm install ansi-styles
+```
+
+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 16/256/truecolor
+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+//       may be degraded to fit that color palette. This means terminals
+//       that do not support 16 million colors will best-match the
+//       original color.
+console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
+console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
+console.log(style.color.ansi16m.hex('#abcdef') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(Not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(Not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `blackBright` (alias: `gray`, `grey`)
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
+
+The following color spaces from `color-convert` are supported:
+
+- `rgb`
+- `hex`
+- `keyword`
+- `hsl`
+- `hsv`
+- `hwb`
+- `ansi`
+- `ansi256`
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
+style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
+
+style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+
+style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
+style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
+```

+## Highlights
+
+- Expressive API
+- Highly performant
+- Ability to nest styles
+- [256/Truecolor color support](#256-and-truecolor-color-support)
+- Auto-detects color support
+- Doesn't extend `String.prototype`
+- Clean and focused
+- Actively maintained
+- [Used by ~50,000 packages](https://www.npmjs.com/browse/depended/chalk) as of January 1, 2020
+
+## Install
+
+```console
+$ npm install chalk
+```
+
+## Usage
+
+```js
+const chalk = require('chalk');
+
+console.log(chalk.blue('Hello world!'));
+```
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+const chalk = require('chalk');
+const log = console.log;
+
+// Combine styled and normal strings
+log(chalk.blue('Hello') + ' World' + chalk.red('!'));
+
+// Compose multiple styles using the chainable API
+log(chalk.blue.bgRed.bold('Hello world!'));
+
+// Pass in multiple arguments
+log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
+
+// Nest styles
+log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
+
+// Nest styles of the same type even (color, underline, background)
+log(chalk.green(
+	'I am a green line ' +
+	chalk.blue.underline.bold('with a blue substring') +
+	' that becomes green again!'
+));
+
+// ES2015 template literal
+log(`
+CPU: ${chalk.red('90%')}
+RAM: ${chalk.green('40%')}
+DISK: ${chalk.yellow('70%')}
+`);
+
+// ES2015 tagged template literal
+log(chalk`
+CPU: {red ${cpu.totalPercent}%}
+RAM: {green ${ram.used / ram.total * 100}%}
+DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
+`);
+
+// Use RGB colors in terminal emulators that support it.
+log(chalk.keyword('orange')('Yay for orange colored text!'));
+log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
+log(chalk.hex('#DEADED').bold('Bold gray!'));
+```
+
+Easily define your own themes:
+
+```js
+const chalk = require('chalk');
+
+const error = chalk.bold.red;
+const warning = chalk.keyword('orange');
+
+console.log(error('Error!'));
+console.log(warning('Warning!'));
+```
+
+Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
+
+```js
+const name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> 'Hello Sindre'
+```
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.level
+
+Specifies the level of color support.
+
+Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+const ctx = new chalk.Instance({level: 0});
+```
+
+| Level | Description |
+| :---: | :--- |
+| `0` | All colors disabled |
+| `1` | Basic color support (16 colors) |
+| `2` | 256 color support |
+| `3` | Truecolor support (16 million colors) |
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
+
+### chalk.stderr and chalk.stderr.supportsColor
+
+`chalk.stderr` contains a separate instance configured with color support detected for `stderr` stream instead of `stdout`. Override rules from `chalk.supportsColor` apply to this too. `chalk.stderr.supportsColor` is exposed for convenience.
+
+## Styles
+
+### Modifiers
+
+- `reset` - Resets the current color chain.
+- `bold` - Make text bold.
+- `dim` - Emitting only a small amount of light.
+- `italic` - Make text italic. *(Not widely supported)*
+- `underline` - Make text underline. *(Not widely supported)*
+- `inverse`- Inverse background and foreground colors.
+- `hidden` - Prints the text, but makes it invisible.
+- `strikethrough` - Puts a horizontal line through the center of the text. *(Not widely supported)*
+- `visible`- Prints the text only when Chalk has a color level > 0. Can be useful for things that are purely cosmetic.
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `blackBright` (alias: `gray`, `grey`)
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+## Tagged template literal
+
+Chalk can be used as a [tagged template literal](https://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
+
+```js
+const chalk = require('chalk');
+
+const miles = 18;
+const calculateFeet = miles => miles * 5280;
+
+console.log(chalk`
+	There are {bold 5280 feet} in a mile.
+	In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
+`);
+```
+
+Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
+
+Template styles are chained exactly like normal Chalk styles. The following three statements are equivalent:
+
+```js
+console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
+console.log(chalk.bold.rgb(10, 100, 200)`Hello!`);
+console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
+```
+
+Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
+
+All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
+
+## 256 and Truecolor color support
+
+Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
+
+Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
+
+Examples:
+
+- `chalk.hex('#DEADED').underline('Hello, world!')`
+- `chalk.keyword('orange')('Some orange text')`
+- `chalk.rgb(15, 100, 204).inverse('Hello!')`
+
+Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
+
+- `chalk.bgHex('#DEADED').underline('Hello, world!')`
+- `chalk.bgKeyword('orange')('Some orange text')`
+- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
+
+The following color models can be used:
+
+- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
+- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
+- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`

+## Windows
+
+If you're on Windows, do yourself a favor and use [Windows Terminal](https://github.com/microsoft/terminal) instead of `cmd.exe`.
+
+## Origin story
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.
+

+# color-convert
+
+[![Build Status](https://travis-ci.org/Qix-/color-convert.svg?branch=master)](https://travis-ci.org/Qix-/color-convert)
+
+Color-convert is a color conversion library for JavaScript and node.
+It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hsl(140, 200, 100);             // [96, 48, 59]
+convert.keyword.rgb('blue');                // [0, 0, 255]
+
+var rgbChannels = convert.rgb.channels;     // 3
+var cmykChannels = convert.cmyk.channels;   // 4
+var ansiChannels = convert.ansi16.channels; // 1
+```
+
+# Install
+
+```console
+$ npm install color-convert
+```
+
+# API
+
+Simply get the property of the _from_ and _to_ conversion that you're looking for.
+
+All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
+
+All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
+
+```js
+var convert = require('color-convert');
+
+// Hex to LAB
+convert.hex.lab('DEADBF');         // [ 76, 21, -2 ]
+convert.hex.lab.raw('DEADBF');     // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
+
+// RGB to CMYK
+convert.rgb.cmyk(167, 255, 4);     // [ 35, 0, 98, 0 ]
+convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
+```
+
+### Arrays
+All functions that accept multiple arguments also support passing an array.
+
+Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hex(123, 45, 67);      // '7B2D43'
+convert.rgb.hex([123, 45, 67]);    // '7B2D43'
+```
+
+## Routing
+
+Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
+
+Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).
+
+# Contribute
+
+If there is a new model you would like to support, or want to add a direct conversion between two existing models, please send us a pull request.

+# lru cache
+
+A cache object that deletes the least-recently-used items.
+
+[![Build Status](https://travis-ci.org/isaacs/node-lru-cache.svg?branch=master)](https://travis-ci.org/isaacs/node-lru-cache) [![Coverage Status](https://coveralls.io/repos/isaacs/node-lru-cache/badge.svg?service=github)](https://coveralls.io/github/isaacs/node-lru-cache)
+
+## Installation:
+
+```javascript
+npm install lru-cache --save
+```
+
+## Usage:
+
+```javascript
+var LRU = require("lru-cache")
+  , options = { max: 500
+              , length: function (n, key) { return n * 2 + key.length }
+              , dispose: function (key, n) { n.close() }
+              , maxAge: 1000 * 60 * 60 }
+  , cache = new LRU(options)
+  , otherCache = new LRU(50) // sets just the max size
+
+cache.set("key", "value")
+cache.get("key") // "value"
+
+// non-string keys ARE fully supported
+// but note that it must be THE SAME object, not
+// just a JSON-equivalent object.
+var someObject = { a: 1 }
+cache.set(someObject, 'a value')
+// Object keys are not toString()-ed
+cache.set('[object Object]', 'a different value')
+assert.equal(cache.get(someObject), 'a value')
+// A similar object with same keys/values won't work,
+// because it's a different object identity
+assert.equal(cache.get({ a: 1 }), undefined)
+
+cache.reset()    // empty the cache
+```
+
+If you put more stuff in it, then items will fall out.
+
+If you try to put an oversized thing in it, then it'll fall out right
+away.
+
+## Options
+
+* `max` The maximum size of the cache, checked by applying the length
+  function to all values in the cache.  Not setting this is kind of
+  silly, since that's the whole purpose of this lib, but it defaults
+  to `Infinity`.  Setting it to a non-number or negative number will
+  throw a `TypeError`.  Setting it to 0 makes it be `Infinity`.
+* `maxAge` Maximum age in ms.  Items are not pro-actively pruned out
+  as they age, but if you try to get an item that is too old, it'll
+  drop it and return undefined instead of giving it to you.
+  Setting this to a negative value will make everything seem old!
+  Setting it to a non-number will throw a `TypeError`.
+* `length` Function that is used to calculate the length of stored
+  items.  If you're storing strings or buffers, then you probably want
+  to do something like `function(n, key){return n.length}`.  The default is
+  `function(){return 1}`, which is fine if you want to store `max`
+  like-sized things.  The item is passed as the first argument, and
+  the key is passed as the second argumnet.
+* `dispose` Function that is called on items when they are dropped
+  from the cache.  This can be handy if you want to close file
+  descriptors or do other cleanup tasks when items are no longer
+  accessible.  Called with `key, value`.  It's called *before*
+  actually removing the item from the internal cache, so if you want
+  to immediately put it back in, you'll have to do that in a
+  `nextTick` or `setTimeout` callback or it won't do anything.
+* `stale` By default, if you set a `maxAge`, it'll only actually pull
+  stale items out of the cache when you `get(key)`.  (That is, it's
+  not pre-emptively doing a `setTimeout` or anything.)  If you set
+  `stale:true`, it'll return the stale value before deleting it.  If
+  you don't set this, then it'll return `undefined` when you try to
+  get a stale entry, as if it had already been deleted.
+* `noDisposeOnSet` By default, if you set a `dispose()` method, then
+  it'll be called whenever a `set()` operation overwrites an existing
+  key.  If you set this option, `dispose()` will only be called when a
+  key falls out of the cache, not when it is overwritten.
+* `updateAgeOnGet` When using time-expiring entries with `maxAge`,
+  setting this to `true` will make each item's effective time update
+  to the current time whenever it is retrieved from cache, causing it
+  to not expire.  (It can still fall out of cache based on recency of
+  use, of course.)
+
+## API
+
+* `set(key, value, maxAge)`
+* `get(key) => value`
+
+    Both of these will update the "recently used"-ness of the key.
+    They do what you think. `maxAge` is optional and overrides the
+    cache `maxAge` option if provided.
+
+    If the key is not found, `get()` will return `undefined`.
+
+    The key and val can be any value.
+
+* `peek(key)`
+
+    Returns the key value (or `undefined` if not found) without
+    updating the "recently used"-ness of the key.
+
+    (If you find yourself using this a lot, you *might* be using the
+    wrong sort of data structure, but there are some use cases where
+    it's handy.)
+
+* `del(key)`
+
+    Deletes a key out of the cache.
+
+* `reset()`
+
+    Clear the cache entirely, throwing away all values.
+
+* `has(key)`
+
+    Check if a key is in the cache, without updating the recent-ness
+    or deleting it for being stale.
+
+* `forEach(function(value,key,cache), [thisp])`
+
+    Just like `Array.prototype.forEach`.  Iterates over all the keys
+    in the cache, in order of recent-ness.  (Ie, more recently used
+    items are iterated over first.)
+
+* `rforEach(function(value,key,cache), [thisp])`
+
+    The same as `cache.forEach(...)` but items are iterated over in
+    reverse order.  (ie, less recently used items are iterated over
+    first.)
+
+* `keys()`
+
+    Return an array of the keys in the cache.
+
+* `values()`
+
+    Return an array of the values in the cache.
+
+* `length`
+
+    Return total length of objects in cache taking into account
+    `length` options function.
+
+* `itemCount`
+
+    Return total quantity of objects currently in cache. Note, that
+    `stale` (see options) items are returned as part of this item
+    count.
+
+* `dump()`
+
+    Return an array of the cache entries ready for serialization and usage
+    with 'destinationCache.load(arr)`.
+
+* `load(cacheEntriesArray)`
+
+    Loads another cache entries array, obtained with `sourceCache.dump()`,
+    into the cache. The destination cache is reset before loading new entries
+
+* `prune()`
+
+    Manually iterates over the entire cache proactively pruning old entries

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash

+````
+
+## Usage
+
+As a node module:
+
+```js

+$ semver -h
+
+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+        Print versions that match the specified range.
+
+-i --increment [<level>]
+        Increment a version by the specified level.  Level can
+        be one of: major, minor, patch, premajor, preminor,
+        prepatch, or prerelease.  Default level is 'patch'.
+        Only one version may be specified.
+
+--preid <identifier>
+        Identifier to be used to prefix premajor, preminor,
+        prepatch or prerelease version increments.
+
+-l --loose
+        Interpret versions and ranges loosely
+
+-n <0|1>
+        This is the base to be used for the prerelease identifier.
+
+-p --include-prerelease
+        Always include prerelease versions in range matching
+
+-c --coerce
+        Coerce a string into SemVer if possible
+        (does not imply --loose)
+
+--rtl
+        Coerce version strings right to left
+
+--ltr
+        Coerce version strings left to right (default)
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<https://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`. The comparator `>1` is equivalent to `>=2.0.0` and
+would match the versions `2.0.0` and `3.1.0`, but not the versions
+`1.0.1` or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+Note that this behavior can be suppressed (treating all prerelease
+versions as if they were normal versions, for the purpose of range
+matching) by setting the `includePrerelease` flag on the options
+object to any
+[functions](https://github.com/npm/node-semver#functions) that do
+range matching.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+#### Prerelease Identifier Base
+
+The method `.inc` takes an optional parameter 'identifierBase' string
+that will let you let your prerelease number as zero-based or one-based.
+Set to `false` to omit the prerelease number altogether.
+If you do not specify this parameter, it will default to zero-based.
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta', '1')
+// '1.2.4-beta.1'
+```
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta', false)
+// '1.2.4-beta'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta -n 1
+1.2.4-beta.1
+```
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta -n false
+1.2.4-beta
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0-0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0-0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any non-prerelease version satisfies, unless
+  `includePrerelease` is specified, in which case any version at all
+  satisfies)
+* `1.x` := `>=1.0.0 <2.0.0-0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0-0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0-0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0-0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0-0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0-0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0-0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0-0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0-0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0-0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0-0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero element in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0-0`
+* `^0.2.3` := `>=0.2.3 <0.3.0-0`
+* `^0.0.3` := `>=0.0.3 <0.0.4-0`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0-0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4-0`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0-0`
+* `^0.0.x` := `>=0.0.0 <0.1.0-0`
+* `^0.0` := `>=0.0.0 <0.1.0-0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0-0`
+* `^0.x` := `>=0.0.0 <1.0.0-0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `options` object argument.  All
+options in this object are `false` by default.  The options supported
+are:
+
+- `loose`  Be more forgiving about not-quite-valid semver strings.
+  (Any resulting output will always be 100% strict compliant, of
+  course.)  For backwards compatibility reasons, if the `options`
+  argument is a boolean value instead of an object, it is interpreted
+  to be the `loose` param.
+- `includePrerelease`  Set to suppress the [default
+  behavior](https://github.com/npm/node-semver#prerelease-tags) of
+  excluding prerelease tagged versions from ranges unless they are
+  explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+  or comparators intersect.
+* `parse(v)`: Attempt to parse a string as a semantic version, returning either
+  a `SemVer` object or `null`.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `compareBuild(v1, v2)`: The same as `compare` but considers `build` when two versions
+  are equal.  Sorts in ascending order if passed to `Array.sort()`.
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minVersion(range)`: Return the lowest version that can possibly match
+  the given range.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+* `simplifyRange(versions, range)`: Return a "simplified" range that
+  matches the same items in `versions` list as the range specified.  Note
+  that it does *not* guarantee that it would match the same versions in all
+  cases, only for the set of versions provided.  This is useful when
+  generating ranges by joining together multiple versions with `||`
+  programmatically, to provide the user with something a bit more
+  ergonomic.  If the provided range is shorter in string-length than the
+  generated range, then that is returned.
+* `subset(subRange, superRange)`: Return `true` if the `subRange` range is
+  entirely contained by the `superRange` range.
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version, options)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver string to
+semver. It looks for the first digit in a string, and consumes all
+remaining characters which satisfy at least a partial semver (e.g., `1`,
+`1.2`, `1.2.3`) up to the max permitted length (256 characters).  Longer
+versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`).  All
+surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
+`3.4.0`).  Only text which lacks digits will fail coercion (`version one`
+is not valid).  The maximum  length for any semver component considered for
+coercion is 16 characters; longer components will be ignored
+(`10000000000000000.4.7.4` becomes `4.7.4`).  The maximum value for any
+semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
+components are invalid (`9999999999999999.4.7.4` is likely invalid).
+
+If the `options.rtl` flag is set, then `coerce` will return the right-most
+coercible tuple that does not share an ending index with a longer coercible
+tuple.  For example, `1.2.3.4` will return `2.3.4` in rtl mode, not
+`4.0.0`.  `1.2.3/4` will return `4.0.0`, because the `4` is not a part of
+any other overlapping SemVer tuple.
+
+### Clean
+
+* `clean(version)`: Clean a string to be a valid semver if possible
+
+This will return a cleaned and trimmed semver version. If the provided
+version is not valid a null will be returned. This does not work for
+ranges.
+
+ex.
+* `s.clean(' = v 2.1.5foo')`: `null`
+* `s.clean(' = v 2.1.5foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean(' = v 2.1.5-foo')`: `null`
+* `s.clean(' = v 2.1.5-foo', { loose: true })`: `'2.1.5-foo'`
+* `s.clean('=v2.1.5')`: `'2.1.5'`
+* `s.clean('  =v2.1.5')`: `2.1.5`
+* `s.clean('      2.1.5   ')`: `'2.1.5'`
+* `s.clean('~1.0.0')`: `null`
+
+## Constants
+
+As a convenience, helper constants are exported to provide information about what `node-semver` supports:
+
+### `RELEASE_TYPES`
+
+- major
+- premajor
+- minor
+- preminor
+- patch
+- prepatch
+- prerelease
+
+```
+const semver = require('semver');
+
+if (semver.RELEASE_TYPES.includes(arbitraryUserInput)) {
+  console.log('This is a valid release type!');
+} else {
+  console.warn('This is NOT a valid release type!');
+}
+```
+
+### `SEMVER_SPEC_VERSION`
+
+2.0.0
+
+```
+const semver = require('semver');
+
+console.log('We are currently using the semver specification version:', semver.SEMVER_SPEC_VERSION);
+```
+
+## Exported Modules
+
+<!--
+TODO: Make sure that all of these items are documented (classes aren't,
+eg), and then pull the module name into the documentation for that specific
+thing.
+-->
+
+You may pull in just the part of this semver utility that you need, if you
+are sensitive to packing and tree-shaking concerns.  The main
+`require('semver')` export uses getter functions to lazily load the parts
