- // Example:
- //
- // bin/compress codemirror runmode javascript xml
- //
- // Will take lib/codemirror.js, addon/runmode/runmode.js,
- // mode/javascript/javascript.js, and mode/xml/xml.js, run them though
- // the online minifier at http://marijnhaverbeke.nl/uglifyjs, and spit
- // out the result.
- //
- // bin/compress codemirror --local /path/to/bin/UglifyJS
- //
- // Will use a local minifier instead of the online default one.
- //
- // Script files are specified without .js ending. Prefixing them with
- // their full (local) path is optional. So you may say lib/codemirror
- // or mode/xml/xml to be more precise. In fact, even the .js suffix
- // may be speficied, if wanted.
