// 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. | ||
