///
/// Reads from stdin & writes to stdout; output can be piped to uglifyjs to 
/// minify/compress the code.
///
/// Examples:
///
/// For CommonJS-style modules, this is usually sufficient:
///   node convert.js < input.js > output.js
///
/// For standalone JS scripts that export a single object/namespace:
///   node convert.js -export:$objectName < input.js > output.js
///
/// If your standalone JS script requires other scripts:
///   node convert.js -dep:package-name:$packageVar -export:$objectName < input.js > output.js
///
