Externalizes the source map found inside a stream to an external `.js.map` file

usage: exorcist map_file [options]

  Externalizes the source map of the file streamed in.

  The source map is written as JSON to map_file, and the original file is streamed out with its
  sourceMappingURL set to the path of map_file (or to the value of the --url option).

OPTIONS:

              --base -b   Base path for calculating relative source paths.
                          (default: use absolute paths)

              --root -r   Root URL for loading relative source paths.
                          Set as sourceRoot in the source map.
                          (default: '')

               --url -u   Full URL to source map.
                          Set as sourceMappingURL in the output stream.
                          (default: map_file)

  --error-on-missing -e   Abort with error if no map is found in the stream.
                          (default: warn but still pipe through source)

EXAMPLE:

  Bundle main.js with browserify into bundle.js and externalize the map to bundle.js.map.

    browserify main.js --debug | exorcist bundle.js.map > bundle.js
