// Compression helper for CodeMirror
//
// Example:
//
// bin/compress codemirror runmode javascript xml
//
// Will take lib/codemirror.js, lib/util/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.
