+## 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)
+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
+
+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)
