+# CC0 1.0 Universal
+
+## Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator and
+subsequent owner(s) (each and all, an “owner”) of an original work of
+authorship and/or a database (each, a “Work”).
+
+Certain owners wish to permanently relinquish those rights to a Work for the
+purpose of contributing to a commons of creative, cultural and scientific works
+(“Commons”) that the public can reliably and without fear of later claims of
+infringement build upon, modify, incorporate in other works, reuse and
+redistribute as freely as possible in any form whatsoever and for any purposes,
+including without limitation commercial purposes. These owners may contribute
+to the Commons to promote the ideal of a free culture and the further
+production of creative, cultural and scientific works, or to gain reputation or
+greater distribution for their Work in part through the use and efforts of
+others.
+
+For these and/or other purposes and motivations, and without any expectation of
+additional consideration or compensation, the person associating CC0 with a
+Work (the “Affirmer”), to the extent that he or she is an owner of Copyright
+and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and
+publicly distribute the Work under its terms, with knowledge of his or her
+Copyright and Related Rights in the Work and the meaning and intended legal
+effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+   protected by copyright and related or neighboring rights (“Copyright and
+   Related Rights”). Copyright and Related Rights include, but are not limited
+   to, the following:
+   1. the right to reproduce, adapt, distribute, perform, display, communicate,
+      and translate a Work;
+   2. moral rights retained by the original author(s) and/or performer(s);
+   3. publicity and privacy rights pertaining to a person’s image or likeness
+      depicted in a Work;
+   4. rights protecting against unfair competition in regards to a Work,
+      subject to the limitations in paragraph 4(i), below;
+   5. rights protecting the extraction, dissemination, use and reuse of data in
+      a Work;
+   6. database rights (such as those arising under Directive 96/9/EC of the
+      European Parliament and of the Council of 11 March 1996 on the legal
+      protection of databases, and under any national implementation thereof,
+      including any amended or successor version of such directive); and
+   7. other similar, equivalent or corresponding rights throughout the world
+      based on applicable law or treaty, and any national implementations
+      thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention of,
+   applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and
+   unconditionally waives, abandons, and surrenders all of Affirmer’s Copyright
+   and Related Rights and associated claims and causes of action, whether now
+   known or unknown (including existing as well as future claims and causes of
+   action), in the Work (i) in all territories worldwide, (ii) for the maximum
+   duration provided by applicable law or treaty (including future time
+   extensions), (iii) in any current or future medium and for any number of
+   copies, and (iv) for any purpose whatsoever, including without limitation
+   commercial, advertising or promotional purposes (the “Waiver”). Affirmer
+   makes the Waiver for the benefit of each member of the public at large and
+   to the detriment of Affirmer’s heirs and successors, fully intending that
+   such Waiver shall not be subject to revocation, rescission, cancellation,
+   termination, or any other legal or equitable action to disrupt the quiet
+   enjoyment of the Work by the public as contemplated by Affirmer’s express
+   Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason be
+   judged legally invalid or ineffective under applicable law, then the Waiver
+   shall be preserved to the maximum extent permitted taking into account
+   Affirmer’s express Statement of Purpose. In addition, to the extent the
+   Waiver is so judged Affirmer hereby grants to each affected person a
+   royalty-free, non transferable, non sublicensable, non exclusive,
+   irrevocable and unconditional license to exercise Affirmer’s Copyright and
+   Related Rights in the Work (i) in all territories worldwide, (ii) for the
+   maximum duration provided by applicable law or treaty (including future time
+   extensions), (iii) in any current or future medium and for any number of
+   copies, and (iv) for any purpose whatsoever, including without limitation
+   commercial, advertising or promotional purposes (the “License”). The License
+   shall be deemed effective as of the date CC0 was applied by Affirmer to the
+   Work. Should any part of the License for any reason be judged legally
+   invalid or ineffective under applicable law, such partial invalidity or
+   ineffectiveness shall not invalidate the remainder of the License, and in
+   such case Affirmer hereby affirms that he or she will not (i) exercise any
+   of his or her remaining Copyright and Related Rights in the Work or (ii)
+   assert any associated claims and causes of action with respect to the Work,
+   in either case contrary to Affirmer’s express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+   1. No trademark or patent rights held by Affirmer are waived, abandoned,
+      surrendered, licensed or otherwise affected by this document.
+   2. Affirmer offers the Work as-is and makes no representations or warranties
+      of any kind concerning the Work, express, implied, statutory or
+      otherwise, including without limitation warranties of title,
+      merchantability, fitness for a particular purpose, non infringement, or
+      the absence of latent or other defects, accuracy, or the present or
+      absence of errors, whether or not discoverable, all to the greatest
+      extent permissible under applicable law.
+   3. Affirmer disclaims responsibility for clearing rights of other persons
+      that may apply to the Work or any use thereof, including without
+      limitation any person’s Copyright and Related Rights in the Work.
+      Further, Affirmer disclaims responsibility for obtaining any necessary
+      consents, permissions or other rights required for any use of the Work.
+   4. Affirmer understands and acknowledges that Creative Commons is not a
+      party to this document and has no duty or obligation with respect to this
+      CC0 or use of the Work.

+# PostCSS image-set() Function [<img src="https://postcss.github.io/postcss/logo.svg" alt="PostCSS Logo" width="90" height="90" align="right">][postcss]
+
+[![NPM Version][npm-img]][npm-url]
+[![CSS Standard Status][css-img]][css-url]
+[![Build Status][cli-img]][cli-url]
+[![Support Chat][git-img]][git-url]
+
+[PostCSS image-set() Function] lets you display resolution-dependent images
+using the `image-set()` function in CSS, following the [CSS Images]
+specification.
+
+```pcss
+.example {
+  background-image: image-set(
+    url(img.png) 1x,
+    url(img@2x.png) 2x,
+    url(img@print.png) 600dpi
+  );
+}
+
+/* becomes */
+
+.example {
+  background-image: url(img.png);
+}
+
+@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) {
+  .example {
+    background-image: url(img@2x.png);
+  }
+}
+
+
+@media (-webkit-min-device-pixel-ratio: 6.25), (min-resolution: 600dpi) {
+  .example {
+    background-image: url(my@print.png);
+  }
+}
+
+.example {
+  background-image: image-set(
+    url(img.png) 1x,
+    url(img@2x.png) 2x,
+    url(img@print.png) 600dpi
+  );
+}
+```
+
+## Usage
+
+Add [PostCSS image-set() Function] to your project:
+
+```bash
+npm install postcss-image-set-function --save-dev
+```
+
+Use [PostCSS image-set() Function] to process your CSS:
+
+```js
+const postcssImageSetFunction = require('postcss-image-set-function');
+
+postcssImageSetFunction.process(YOUR_CSS /*, processOptions, pluginOptions */);
+```
+
+Or use it as a [PostCSS] plugin:
+
+```js
+const postcss = require('postcss');
+const postcssImageSetFunction = require('postcss-image-set-function');
+
+postcss([
+  postcssImageSetFunction(/* pluginOptions */)
+]).process(YOUR_CSS /*, processOptions */);
+```
+
+[PostCSS image-set() Function] runs in all Node environments, with special
+instructions for:
+
+| [Node](INSTALL.md#node) | [PostCSS CLI](INSTALL.md#postcss-cli) | [Webpack](INSTALL.md#webpack) | [Create React App](INSTALL.md#create-react-app) | [Gulp](INSTALL.md#gulp) | [Grunt](INSTALL.md#grunt) |
+| --- | --- | --- | --- | --- | --- |
+
+## Options
+
+### preserve
+
+The `preserve` option determines whether the original declaration using
+`image-set()` is preserved. By default, it is preserved.
+
+```js
+postcssImageSetFunction({ preserve: false })
+```
+
+```pcss
+.example {
+  background-image: image-set(
+    url(img.png) 1x,
+    url(img@2x.png) 2x,
+    url(img@print.png) 600dpi
+  );
+}
+
+/* becomes */
+
+.example {
+  background-image: url(img.png);
+}
+
+@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) {
+  .example {
+    background-image: url(img@2x.png);
+  }
+}
+
+
+@media (-webkit-min-device-pixel-ratio: 6.25), (min-resolution: 600dpi) {
+  .example {
+    background-image: url(my@print.png);
+  }
+}
+```
+
+### onvalid
+
+The `oninvalid` option determines how invalid usage of `image-set()` should be
+handled. By default, invalid usages of `image-set()` are ignored. They can be
+configured to display a `warning` or `throw` an error.
+
+```js
+postcssImageSetFunction({ oninvalid: 'warning' }) // warn on invalid usages
+```
+
+```js
+postcssImageSetFunction({ oninvalid: 'throw' }) // throw on invalid usages
+```
+
+## Image Resolution
+
+The `image-set()` function allows an author to provide multiple resolutions of
+an image and let the browser decide which is most appropriate in a given
+situation. The `image-set()` also never fails to choose an image; the
+`<resolution>` just helps determine which of the images is chosen.
+
+Since this plugin is not a browser, the image options are sorted by device
+pixel ratio and the lowest ratio is used as the default, while the remaining
+images are pushed behind media queries.
+
+Therefore, this plugin can only approximate native browser behavior. While
+images should typically match the resolution as the device they’re being viewed
+in, other factors can affect the chosen image. For example, if the user is on a
+slow mobile connection, the browser may prefer to select a lower-res image
+rather than wait for a larger, resolution-matching image to load.

+# picocolors
+
+    npm install picocolors
+
+A tinier and faster alternative to [nanocolors](https://github.com/ai/nanocolors). Andrey, are you even trying?
+
+```javascript
+import pc from "picocolors";
+
+console.log(pc.green(`How are ${pc.italic(`you`)} doing?`));
+```
+
+- Up to [2x faster and 2x smaller](#benchmarks) than alternatives
+- 3x faster and 10x smaller than `chalk`
+- [TypeScript](https://www.typescriptlang.org/) support
+- [`NO_COLOR`](https://no-color.org/) friendly
+- Node.js v6+ & browsers support
+- The same API, but faster, much faster
+- No `String.prototype` modifications (anyone still doing it?)
+- No dependencies and the smallest `node_modules` footprint

+
+PostCSS is a tool for transforming styles with JS plugins.
+These plugins can lint your CSS, support variables and mixins,
+transpile future CSS syntax, inline images, and more.
+
+PostCSS is used by industry leaders including Wikipedia, Twitter, Alibaba,
+and JetBrains. The [Autoprefixer] PostCSS plugin is one of the most popular
+CSS processors.
+
+PostCSS takes a CSS file and provides an API to analyze and modify its rules
+(by transforming them into an [Abstract Syntax Tree]).
+This API can then be used by [plugins] to do a lot of useful things,
+e.g. to find errors automatically insert vendor prefixes.

+   *   and `{` for at-rules.
+   * * `semicolon`: contains true if the last child has

+# Change Log
+
+## 0.5.6
+
+* Fix for regression when people were using numbers as names in source maps. See
+  #236.
+
+## 0.5.5
+
+* Fix "regression" of unsupported, implementation behavior that half the world
+  happens to have come to depend on. See #235.
+
+* Fix regression involving function hoisting in SpiderMonkey. See #233.
+
+## 0.5.4
+
+* Large performance improvements to source-map serialization. See #228 and #229.
+
+## 0.5.3
+
+* Do not include unnecessary distribution files. See
+  commit ef7006f8d1647e0a83fdc60f04f5a7ca54886f86.
+
+## 0.5.2
+
+* Include browser distributions of the library in package.json's `files`. See
+  issue #212.
+
+## 0.5.1
+
+* Fix latent bugs in IndexedSourceMapConsumer.prototype._parseMappings. See
+  ff05274becc9e6e1295ed60f3ea090d31d843379.
+
+## 0.5.0
+
+* Node 0.8 is no longer supported.
+
+* Use webpack instead of dryice for bundling.
+
+* Big speedups serializing source maps. See pull request #203.
+
+* Fix a bug with `SourceMapConsumer.prototype.sourceContentFor` and sources that
+  explicitly start with the source root. See issue #199.
+
+## 0.4.4
+
+* Fix an issue where using a `SourceMapGenerator` after having created a
+  `SourceMapConsumer` from it via `SourceMapConsumer.fromSourceMap` failed. See
+  issue #191.
+
+* Fix an issue with where `SourceMapGenerator` would mistakenly consider
+  different mappings as duplicates of each other and avoid generating them. See
+  issue #192.
+
+## 0.4.3
+
+* A very large number of performance improvements, particularly when parsing
+  source maps. Collectively about 75% of time shaved off of the source map
+  parsing benchmark!
+
+* Fix a bug in `SourceMapConsumer.prototype.allGeneratedPositionsFor` and fuzzy
+  searching in the presence of a column option. See issue #177.
+
+* Fix a bug with joining a source and its source root when the source is above
+  the root. See issue #182.
+
+* Add the `SourceMapConsumer.prototype.hasContentsOfAllSources` method to
+  determine when all sources' contents are inlined into the source map. See
+  issue #190.
+
+## 0.4.2
+
+* Add an `.npmignore` file so that the benchmarks aren't pulled down by
+  dependent projects. Issue #169.
+
+* Add an optional `column` argument to
+  `SourceMapConsumer.prototype.allGeneratedPositionsFor` and better handle lines
+  with no mappings. Issues #172 and #173.
+
+## 0.4.1
+
+* Fix accidentally defining a global variable. #170.
+
+## 0.4.0
+
+* The default direction for fuzzy searching was changed back to its original
+  direction. See #164.
+
+* There is now a `bias` option you can supply to `SourceMapConsumer` to control
+  the fuzzy searching direction. See #167.
+
+* About an 8% speed up in parsing source maps. See #159.
+
+* Added a benchmark for parsing and generating source maps.
+
+## 0.3.0
+
+* Change the default direction that searching for positions fuzzes when there is
+  not an exact match. See #154.
+
+* Support for environments using json2.js for JSON serialization. See #156.
+
+## 0.2.0
+
+* Support for consuming "indexed" source maps which do not have any remote
+  sections. See pull request #127. This introduces a minor backwards
+  incompatibility if you are monkey patching `SourceMapConsumer.prototype`
+  methods.
+
+## 0.1.43
+
+* Performance improvements for `SourceMapGenerator` and `SourceNode`. See issue
+  #148 for some discussion and issues #150, #151, and #152 for implementations.
+
+## 0.1.42
+
+* Fix an issue where `SourceNode`s from different versions of the source-map
+  library couldn't be used in conjunction with each other. See issue #142.
+
+## 0.1.41
+
+* Fix a bug with getting the source content of relative sources with a "./"
+  prefix. See issue #145 and [Bug 1090768](bugzil.la/1090768).
+
+* Add the `SourceMapConsumer.prototype.computeColumnSpans` method to compute the
+  column span of each mapping.
+
+* Add the `SourceMapConsumer.prototype.allGeneratedPositionsFor` method to find
+  all generated positions associated with a given original source and line.
+
+## 0.1.40
+
+* Performance improvements for parsing source maps in SourceMapConsumer.
+
+## 0.1.39
+
+* Fix a bug where setting a source's contents to null before any source content
+  had been set before threw a TypeError. See issue #131.
+
+## 0.1.38
+
+* Fix a bug where finding relative paths from an empty path were creating
+  absolute paths. See issue #129.
+
+## 0.1.37
+
+* Fix a bug where if the source root was an empty string, relative source paths
+  would turn into absolute source paths. Issue #124.
+
+## 0.1.36
+
+* Allow the `names` mapping property to be an empty string. Issue #121.
+
+## 0.1.35
+
+* A third optional parameter was added to `SourceNode.fromStringWithSourceMap`
+  to specify a path that relative sources in the second parameter should be
+  relative to. Issue #105.
+
+* If no file property is given to a `SourceMapGenerator`, then the resulting
+  source map will no longer have a `null` file property. The property will
+  simply not exist. Issue #104.
+
+* Fixed a bug where consecutive newlines were ignored in `SourceNode`s.
+  Issue #116.
+
+## 0.1.34
+
+* Make `SourceNode` work with windows style ("\r\n") newlines. Issue #103.
+
+* Fix bug involving source contents and the
+  `SourceMapGenerator.prototype.applySourceMap`. Issue #100.
+
+## 0.1.33
+
+* Fix some edge cases surrounding path joining and URL resolution.
+
+* Add a third parameter for relative path to
+  `SourceMapGenerator.prototype.applySourceMap`.
+
+* Fix issues with mappings and EOLs.
+
+## 0.1.32
+
+* Fixed a bug where SourceMapConsumer couldn't handle negative relative columns
+  (issue 92).
+
+* Fixed test runner to actually report number of failed tests as its process
+  exit code.
+
+* Fixed a typo when reporting bad mappings (issue 87).
+
+## 0.1.31
+
+* Delay parsing the mappings in SourceMapConsumer until queried for a source
+  location.
+
+* Support Sass source maps (which at the time of writing deviate from the spec
+  in small ways) in SourceMapConsumer.
+
+## 0.1.30
+
+* Do not join source root with a source, when the source is a data URI.
+
+* Extend the test runner to allow running single specific test files at a time.
+
+* Performance improvements in `SourceNode.prototype.walk` and
+  `SourceMapConsumer.prototype.eachMapping`.
+
+* Source map browser builds will now work inside Workers.
+
+* Better error messages when attempting to add an invalid mapping to a
+  `SourceMapGenerator`.
+
+## 0.1.29
+
+* Allow duplicate entries in the `names` and `sources` arrays of source maps
+  (usually from TypeScript) we are parsing. Fixes github issue 72.
+
+## 0.1.28
+
+* Skip duplicate mappings when creating source maps from SourceNode; github
+  issue 75.
+
+## 0.1.27
+
+* Don't throw an error when the `file` property is missing in SourceMapConsumer,
+  we don't use it anyway.
+
+## 0.1.26
+
+* Fix SourceNode.fromStringWithSourceMap for empty maps. Fixes github issue 70.
+
+## 0.1.25
+
+* Make compatible with browserify
+
+## 0.1.24
+
+* Fix issue with absolute paths and `file://` URIs. See
+  https://bugzilla.mozilla.org/show_bug.cgi?id=885597
+
+## 0.1.23
+
+* Fix issue with absolute paths and sourcesContent, github issue 64.
+
+## 0.1.22
+
+* Ignore duplicate mappings in SourceMapGenerator. Fixes github issue 21.
+
+## 0.1.21
+
+* Fixed handling of sources that start with a slash so that they are relative to
+  the source root's host.
+
+## 0.1.20
+
+* Fixed github issue #43: absolute URLs aren't joined with the source root
+  anymore.

+
+In depth guide:
+[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)
+
+#### With SourceNode (high level API)
+
+```js
+function compile(ast) {
+  switch (ast.type) {
+  case 'BinaryExpression':
+    return new SourceNode(
+      ast.location.line,
+      ast.location.column,
+      ast.location.source,
+      [compile(ast.left), " + ", compile(ast.right)]
+    );
+  case 'Literal':
+    return new SourceNode(
+      ast.location.line,
+      ast.location.column,
+      ast.location.source,
+      String(ast.value)
+    );
+  // ...
+  default:
+    throw new Error("Bad AST");
+  }
+}
+
+var ast = parse("40 + 2", "add.js");
+console.log(compile(ast).toStringWithSourceMap({
+  file: 'add.js'
+}));
+// { code: '40 + 2',
+//   map: [object SourceMapGenerator] }
+```
+
+#### With SourceMapGenerator (low level API)
+
+```js
+var map = new SourceMapGenerator({
+  file: "source-mapped.js"
+});
+
+map.addMapping({
+  generated: {
+    line: 10,
+    column: 35
+  },
+  source: "foo.js",
+  original: {
+    line: 33,
+    column: 2
+  },
+  name: "christopher"
+});
+
+console.log(map.toString());
+// '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
+```
+
+## API
+
+Get a reference to the module:
+
+```js
+// Node.js
+var sourceMap = require('source-map');
+
+// Browser builds
+var sourceMap = window.sourceMap;
+
+// Inside Firefox
+const sourceMap = require("devtools/toolkit/sourcemap/source-map.js");
+```
+
+### SourceMapConsumer
+
+A SourceMapConsumer instance represents a parsed source map which we can query
+for information about the original file positions by giving it a file position
+in the generated source.
+
+#### new SourceMapConsumer(rawSourceMap)
+
+The only parameter is the raw source map (either as a string which can be
+`JSON.parse`'d, or an object). According to the spec, source maps have the
+following attributes:
+
+* `version`: Which version of the source map spec this map is following.
+
+* `sources`: An array of URLs to the original source files.
+
+* `names`: An array of identifiers which can be referenced by individual
+  mappings.
+
+* `sourceRoot`: Optional. The URL root from which all sources are relative.
+
+* `sourcesContent`: Optional. An array of contents of the original source files.
+
+* `mappings`: A string of base64 VLQs which contain the actual mappings.
+
+* `file`: Optional. The generated filename this source map is associated with.
+
+```js
+var consumer = new sourceMap.SourceMapConsumer(rawSourceMapJsonData);
+```
+
+#### SourceMapConsumer.prototype.computeColumnSpans()
+
+Compute the last column for each generated mapping. The last column is
+inclusive.
+
+```js
+// Before:
+consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1 },
+//   { line: 2,
+//     column: 10 },
+//   { line: 2,
+//     column: 20 } ]
+
+consumer.computeColumnSpans();
+
+// After:
+consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1,
+//     lastColumn: 9 },
+//   { line: 2,
+//     column: 10,
+//     lastColumn: 19 },
+//   { line: 2,
+//     column: 20,
+//     lastColumn: Infinity } ]
+
+```
+
+#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
+
+Returns the original source, line, and column information for the generated
+source's line and column positions provided. The only argument is an object with
+the following properties:
+
+* `line`: The line number in the generated source.  Line numbers in
+  this library are 1-based (note that the underlying source map
+  specification uses 0-based line numbers -- this library handles the
+  translation).
+
+* `column`: The column number in the generated source.  Column numbers
+  in this library are 0-based.
+
+* `bias`: Either `SourceMapConsumer.GREATEST_LOWER_BOUND` or
+  `SourceMapConsumer.LEAST_UPPER_BOUND`. Specifies whether to return the closest
+  element that is smaller than or greater than the one we are searching for,
+  respectively, if the exact element cannot be found.  Defaults to
+  `SourceMapConsumer.GREATEST_LOWER_BOUND`.
+
+and an object is returned with the following properties:
+
+* `source`: The original source file, or null if this information is not
+  available.
+
+* `line`: The line number in the original source, or null if this information is
+  not available.  The line number is 1-based.
+
+* `column`: The column number in the original source, or null if this
+  information is not available.  The column number is 0-based.
+
+* `name`: The original identifier, or null if this information is not available.
+
+```js
+consumer.originalPositionFor({ line: 2, column: 10 })
+// { source: 'foo.coffee',
+//   line: 2,
+//   column: 2,
+//   name: null }
+
+consumer.originalPositionFor({ line: 99999999999999999, column: 999999999999999 })
+// { source: null,
+//   line: null,
+//   column: null,
+//   name: null }
+```
+
+#### SourceMapConsumer.prototype.generatedPositionFor(originalPosition)
+
+Returns the generated line and column information for the original source,
+line, and column positions provided. The only argument is an object with
+the following properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.  The line number is
+  1-based.
+
+* `column`: The column number in the original source.  The column
+  number is 0-based.
+
+and an object is returned with the following properties:
+
+* `line`: The line number in the generated source, or null.  The line
+  number is 1-based.
+
+* `column`: The column number in the generated source, or null.  The
+  column number is 0-based.
+
+```js
+consumer.generatedPositionFor({ source: "example.js", line: 2, column: 10 })
+// { line: 1,
+//   column: 56 }
+```
+
+#### SourceMapConsumer.prototype.allGeneratedPositionsFor(originalPosition)
+
+Returns all generated line and column information for the original source, line,
+and column provided. If no column is provided, returns all mappings
+corresponding to a either the line we are searching for or the next closest line
+that has any mappings. Otherwise, returns all mappings corresponding to the
+given line and either the column we are searching for or the next closest column
+that has any offsets.
+
+The only argument is an object with the following properties:
+
+* `source`: The filename of the original source.
+
+* `line`: The line number in the original source.  The line number is
+  1-based.
+
+* `column`: Optional. The column number in the original source.  The
+  column number is 0-based.
+
+and an array of objects is returned, each with the following properties:
+
+* `line`: The line number in the generated source, or null.  The line
+  number is 1-based.
+
+* `column`: The column number in the generated source, or null.  The
+  column number is 0-based.
+
+```js
+consumer.allGeneratedpositionsfor({ line: 2, source: "foo.coffee" })
+// [ { line: 2,
+//     column: 1 },
+//   { line: 2,
+//     column: 10 },
+//   { line: 2,
+//     column: 20 } ]
+```
+
+#### SourceMapConsumer.prototype.hasContentsOfAllSources()
+
+Return true if we have the embedded source content for every source listed in
+the source map, false otherwise.
+
+In other words, if this method returns `true`, then
+`consumer.sourceContentFor(s)` will succeed for every source `s` in
+`consumer.sources`.
+
+```js
+// ...
+if (consumer.hasContentsOfAllSources()) {
+  consumerReadyCallback(consumer);
+} else {
+  fetchSources(consumer, consumerReadyCallback);
+}
+// ...
+```
+
+#### SourceMapConsumer.prototype.sourceContentFor(source[, returnNullOnMissing])
+
+Returns the original source content for the source provided. The only
+argument is the URL of the original source file.
+
+If the source content for the given source is not found, then an error is
+thrown. Optionally, pass `true` as the second param to have `null` returned
+instead.
+
+```js
+consumer.sources
+// [ "my-cool-lib.clj" ]
+
+consumer.sourceContentFor("my-cool-lib.clj")
+// "..."
+
+consumer.sourceContentFor("this is not in the source map");
+// Error: "this is not in the source map" is not in the source map
+
+consumer.sourceContentFor("this is not in the source map", true);
+// null
+```
+
+#### SourceMapConsumer.prototype.eachMapping(callback, context, order)
+
+Iterate over each mapping between an original source/line/column and a
+generated line/column in this source map.
+
+* `callback`: The function that is called with each mapping. Mappings have the
+  form `{ source, generatedLine, generatedColumn, originalLine, originalColumn,
+  name }`
+
+* `context`: Optional. If specified, this object will be the value of `this`
+  every time that `callback` is called.
+
+* `order`: Either `SourceMapConsumer.GENERATED_ORDER` or
+  `SourceMapConsumer.ORIGINAL_ORDER`. Specifies whether you want to iterate over
+  the mappings sorted by the generated file's line/column order or the
+  original's source/line/column order, respectively. Defaults to
+  `SourceMapConsumer.GENERATED_ORDER`.
+
+```js
+consumer.eachMapping(function (m) { console.log(m); })
+// ...
+// { source: 'illmatic.js',
+//   generatedLine: 1,
+//   generatedColumn: 0,
+//   originalLine: 1,
+//   originalColumn: 0,
+//   name: null }
+// { source: 'illmatic.js',
+//   generatedLine: 2,
+//   generatedColumn: 0,
+//   originalLine: 2,
+//   originalColumn: 0,
+//   name: null }
+// ...
+```
+### SourceMapGenerator
+
+An instance of the SourceMapGenerator represents a source map which is being
+built incrementally.
+
+#### new SourceMapGenerator([startOfSourceMap])
+
+You may pass an object with the following properties:
+
+* `file`: The filename of the generated source that this source map is
+  associated with.
+
+* `sourceRoot`: A root for all relative URLs in this source map.
+
+* `skipValidation`: Optional. When `true`, disables validation of mappings as
+  they are added. This can improve performance but should be used with
+  discretion, as a last resort. Even then, one should avoid using this flag when
+  running tests, if possible.
+
+```js
+var generator = new sourceMap.SourceMapGenerator({
+  file: "my-generated-javascript-file.js",
+  sourceRoot: "http://example.com/app/js/"
+});
+```
+
+#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
+
+Creates a new `SourceMapGenerator` from an existing `SourceMapConsumer` instance.
+
+* `sourceMapConsumer` The SourceMap.
+
+```js
+var generator = sourceMap.SourceMapGenerator.fromSourceMap(consumer);
+```
+
+#### SourceMapGenerator.prototype.addMapping(mapping)
+
+Add a single mapping from original source line and column to the generated
+source's line and column for this source map being created. The mapping object
+should have the following properties:
+
+* `generated`: An object with the generated line and column positions.
+
+* `original`: An object with the original line and column positions.
+
+* `source`: The original source file (relative to the sourceRoot).
+
+* `name`: An optional original token name for this mapping.
+
+```js
+generator.addMapping({
+  source: "module-one.scm",
+  original: { line: 128, column: 0 },
+  generated: { line: 3, column: 456 }
+})
+```
+
+#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for an original source file.
+
+* `sourceFile` the URL of the original source file.
+
+* `sourceContent` the content of the source file.
+
+```js
+generator.setSourceContent("module-one.scm",
+                           fs.readFileSync("path/to/module-one.scm"))
+```
+
+#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile[, sourceMapPath]])
+
+Applies a SourceMap for a source file to the SourceMap.
+Each mapping to the supplied source file is rewritten using the
+supplied SourceMap. Note: The resolution for the resulting mappings
+is the minimum of this map and the supplied map.
+
+* `sourceMapConsumer`: The SourceMap to be applied.
+
+* `sourceFile`: Optional. The filename of the source file.
+  If omitted, sourceMapConsumer.file will be used, if it exists.
+  Otherwise an error will be thrown.
+
+* `sourceMapPath`: Optional. The dirname of the path to the SourceMap
+  to be applied. If relative, it is relative to the SourceMap.
+
+  This parameter is needed when the two SourceMaps aren't in the same
+  directory, and the SourceMap to be applied contains relative source
+  paths. If so, those relative source paths need to be rewritten
+  relative to the SourceMap.
+
+  If omitted, it is assumed that both SourceMaps are in the same directory,
+  thus not needing any rewriting. (Supplying `'.'` has the same effect.)
+
+#### SourceMapGenerator.prototype.toString()
+
+Renders the source map being generated to a string.
+
+```js
+generator.toString()
+// '{"version":3,"sources":["module-one.scm"],"names":[],"mappings":"...snip...","file":"my-generated-javascript-file.js","sourceRoot":"http://example.com/app/js/"}'
+```
+
+### SourceNode
+
+SourceNodes provide a way to abstract over interpolating and/or concatenating
+snippets of generated JavaScript source code, while maintaining the line and
+column information associated between those snippets and the original source
+code. This is useful as the final intermediate representation a compiler might
+use before outputting the generated JS and source map.
+
+#### new SourceNode([line, column, source[, chunk[, name]]])
+
+* `line`: The original line number associated with this source node, or null if
+  it isn't associated with an original line.  The line number is 1-based.
+
+* `column`: The original column number associated with this source node, or null
+  if it isn't associated with an original column.  The column number
+  is 0-based.
+
+* `source`: The original source's filename; null if no filename is provided.
+
+* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
+  below.
+
+* `name`: Optional. The original identifier.
+
+```js
+var node = new SourceNode(1, 2, "a.cpp", [
+  new SourceNode(3, 4, "b.cpp", "extern int status;\n"),
+  new SourceNode(5, 6, "c.cpp", "std::string* make_string(size_t n);\n"),
+  new SourceNode(7, 8, "d.cpp", "int main(int argc, char** argv) {}\n"),
+]);
+```
+
+#### SourceNode.fromStringWithSourceMap(code, sourceMapConsumer[, relativePath])
+
+Creates a SourceNode from generated code and a SourceMapConsumer.
+
+* `code`: The generated code
+
+* `sourceMapConsumer` The SourceMap for the generated code
+
+* `relativePath` The optional path that relative sources in `sourceMapConsumer`
+  should be relative to.
+
+```js
+var consumer = new SourceMapConsumer(fs.readFileSync("path/to/my-file.js.map", "utf8"));
+var node = SourceNode.fromStringWithSourceMap(fs.readFileSync("path/to/my-file.js"),
+                                              consumer);
+```
+
+#### SourceNode.prototype.add(chunk)
+
+Add a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+   `SourceNode`, or an array where each member is one of those things.
+
+```js
+node.add(" + ");
+node.add(otherNode);
+node.add([leftHandOperandNode, " + ", rightHandOperandNode]);
+```
+
+#### SourceNode.prototype.prepend(chunk)
+
+Prepend a chunk of generated JS to this source node.
+
+* `chunk`: A string snippet of generated JS code, another instance of
+   `SourceNode`, or an array where each member is one of those things.
+
+```js
+node.prepend("/** Build Id: f783haef86324gf **/\n\n");
+```
+
+#### SourceNode.prototype.setSourceContent(sourceFile, sourceContent)
+
+Set the source content for a source file. This will be added to the
+`SourceMap` in the `sourcesContent` field.
+
+* `sourceFile`: The filename of the source file
+
+* `sourceContent`: The content of the source file
+
+```js
+node.setSourceContent("module-one.scm",
+                      fs.readFileSync("path/to/module-one.scm"))
+```
+
+#### SourceNode.prototype.walk(fn)
+
+Walk over the tree of JS snippets in this node and its children. The walking
+function is called once for each snippet of JS and is passed that snippet and
+the its original associated source's line/column location.
+
+* `fn`: The traversal function.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.walk(function (code, loc) { console.log("WALK:", code, loc); })
+// WALK: uno { source: 'b.js', line: 3, column: 4, name: null }
+// WALK: dos { source: 'a.js', line: 1, column: 2, name: null }
+// WALK: tres { source: 'a.js', line: 1, column: 2, name: null }
+// WALK: quatro { source: 'c.js', line: 5, column: 6, name: null }
+```
+
+#### SourceNode.prototype.walkSourceContents(fn)
+
+Walk over the tree of SourceNodes. The walking function is called for each
+source file content and is passed the filename and source content.
+
+* `fn`: The traversal function.
+
+```js
+var a = new SourceNode(1, 2, "a.js", "generated from a");
+a.setSourceContent("a.js", "original a");
+var b = new SourceNode(1, 2, "b.js", "generated from b");
+b.setSourceContent("b.js", "original b");
+var c = new SourceNode(1, 2, "c.js", "generated from c");
+c.setSourceContent("c.js", "original c");
+
+var node = new SourceNode(null, null, null, [a, b, c]);
+node.walkSourceContents(function (source, contents) { console.log("WALK:", source, ":", contents); })
+// WALK: a.js : original a
+// WALK: b.js : original b
+// WALK: c.js : original c
+```
+
+#### SourceNode.prototype.join(sep)
+
+Like `Array.prototype.join` except for SourceNodes. Inserts the separator
+between each of this source node's children.
+
+* `sep`: The separator.
+
+```js
+var lhs = new SourceNode(1, 2, "a.rs", "my_copy");
+var operand = new SourceNode(3, 4, "a.rs", "=");
+var rhs = new SourceNode(5, 6, "a.rs", "orig.clone()");
+
+var node = new SourceNode(null, null, null, [ lhs, operand, rhs ]);
+var joinedNode = node.join(" ");
+```
+
+#### SourceNode.prototype.replaceRight(pattern, replacement)
+
+Call `String.prototype.replace` on the very right-most source snippet. Useful
+for trimming white space from the end of a source node, etc.
+
+* `pattern`: The pattern to replace.
+
+* `replacement`: The thing to replace the pattern with.
+
+```js
+// Trim trailing white space.
+node.replaceRight(/\s*$/, "");
+```
+
+#### SourceNode.prototype.toString()
+
+Return the string representation of this source node. Walks over the tree and
+concatenates all the various snippets together to one string.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.toString()
+// 'unodostresquatro'
+```
+
+#### SourceNode.prototype.toStringWithSourceMap([startOfSourceMap])
+
+Returns the string representation of this tree of source nodes, plus a
+SourceMapGenerator which contains all the mappings between the generated and
+original sources.
+
+The arguments are the same as those to `new SourceMapGenerator`.
+
+```js
+var node = new SourceNode(1, 2, "a.js", [
+  new SourceNode(3, 4, "b.js", "uno"),
+  "dos",
+  [
+    "tres",
+    new SourceNode(5, 6, "c.js", "quatro")
+  ]
+]);
+
+node.toStringWithSourceMap({ file: "my-output-file.js" })
