-# babel-generator
-
-> Turns an AST into code.
-
-## Install
-
-```sh
-npm install --save-dev babel-generator
-```
-
-## Usage
-
-```js
-import {parse} from 'babylon';
-import generate from 'babel-generator';
-
-const code = 'class Example {}';
-const ast = parse(code);
-
-const output = generate(ast, { /* options */ }, code);
-```
-
-## Options
-
-Options for formatting output:
-
-name                   | type     | default         | description
------------------------|----------|-----------------|--------------------------------------------------------------------------
-auxiliaryCommentBefore | string   |                 | Optional string to add as a block comment at the start of the output file
-auxiliaryCommentAfter  | string   |                 | Optional string to add as a block comment at the end of the output file
-shouldPrintComment     | function | `opts.comments` | Function that takes a comment (as a string) and returns `true` if the comment should be included in the output.  By default, comments are included if `opts.comments` is `true` or if `opts.minifed` is `false` and the comment contains `@preserve` or `@license`
-retainLines            | boolean  | `false`         | Attempt to use the same line numbers in the output code as in the source code (helps preserve stack traces)
-retainFunctionParens   | boolean  | `false`         | Retain parens around function expressions (could be used to change engine parsing behavior)
-comments               | boolean  | `true`          | Should comments be included in output
-compact                | boolean or `'auto'` | `opts.minified` | Set to `true` to avoid adding whitespace for formatting
-minified               | boolean  | `false`         | Should the output be minified
-concise                | boolean  | `false`         | Set to `true` to reduce whitespace (but not as much as `opts.compact`)
-quotes                 | `'single'` or `'double'` | autodetect based on `ast.tokens` | The type of quote to use in the output
-filename               | string   |                 | Used in warning messages
-flowCommaSeparator     | boolean  | `false`         | Set to `true` to use commas instead of semicolons as Flow property separators
-jsonCompatibleStrings  | boolean  | `false`         | Set to true to run `jsesc` with "json": true to print "\u00A9" vs. "©";
-
-Options for source maps:
-
-name                   | type     | default         | description
------------------------|----------|-----------------|--------------------------------------------------------------------------
-sourceMaps             | boolean  | `false`         | Enable generating source maps
-sourceMapTarget        | string   |                 | The filename of the generated code that the source map will be associated with
-sourceRoot             | string   |                 | A root for all relative URLs in the source map
-sourceFileName         | string   |                 | The filename for the source code (i.e. the code in the `code` argument).  This will only be used if `code` is a string.
-
-## AST from Multiple Sources
-
-In most cases, Babel does a 1:1 transformation of input-file to output-file.  However,
-you may be dealing with AST constructed from multiple sources - JS files, templates, etc.
-If this is the case, and you want the sourcemaps to reflect the correct sources, you'll need
-to pass an object to `generate` as the `code` parameter.  Keys
-should be the source filenames, and values should be the source content.
-
-Here's an example of what that might look like:
-
-```js
-import {parse} from 'babylon';
-import generate from 'babel-generator';
-
-const a = 'var a = 1;';
-const b = 'var b = 2;';
-const astA = parse(a, { sourceFilename: 'a.js' });
-const astB = parse(b, { sourceFilename: 'b.js' });
-const ast = {
-  type: 'Program',
-  body: [].concat(astA.program.body, astB.program.body)
-};
-
-const { code, map } = generate(ast, { sourceMaps: true }, {
-  'a.js': a,
-  'b.js': b
-});
-
-// Sourcemap will point to both a.js and b.js where appropriate.

-# babel-template
-
-> Generate an AST from a string template.
-
-In computer science, this is known as an implementation of quasiquotes.
-
-## Install
-
-```sh
-npm install --save-dev babel-template
-```
-
-## Usage
-
-```js
-import template from "babel-template";
-import generate from "babel-generator";
-import * as t from "babel-types";
-
-const buildRequire = template(`
-  var IMPORT_NAME = require(SOURCE);
-`);
-
-const ast = buildRequire({
-  IMPORT_NAME: t.identifier("myModule"),
-  SOURCE: t.stringLiteral("my-module")
-});
-
-console.log(generate(ast).code);
-```
-
-```js
-const myModule = require("my-module");
-```
-
-## API
-
-### `template(code, [opts])`
-
-#### code
-
-Type: `string`
-
-#### options
-
-`babel-template` accepts all of the options from [babylon], and specifies
-some defaults of its own:
-
-* `allowReturnOutsideFunction` is set to `true` by default.
-* `allowSuperOutsideMethod` is set to `true` by default.
-
-##### preserveComments
-
-Type: `boolean`
-Default: `false`
-
-Set this to `true` to preserve any comments from the `code` parameter.
-
-#### Return value
-
-`babel-template` returns a `function` which is invoked with an optional object
-of replacements. See the usage section for an example.

-# babel-traverse
-
-> babel-traverse maintains the overall tree state, and is responsible for replacing, removing, and adding nodes.
-
-## Install
-
-```sh
-$ npm install --save babel-traverse
-```
-
-## Usage
-
-We can use it alongside Babylon to traverse and update nodes:
-
-```js
-import * as babylon from "babylon";
-import traverse from "babel-traverse";
-
-const code = `function square(n) {
-  return n * n;
-}`;
-
-const ast = babylon.parse(code);
-
-traverse(ast, {
-  enter(path) {
-    if (path.isIdentifier({ name: "n" })) {
-      path.node.name = "x";
-    }
-  }
-});
-```
