id:oppara:20070430
いろいろアップデートしてたので

• JavaScript-C 1.8.0 pre-release 1 2009-02-16
• JsDecoder.js 1.1.0

// usage: $ js -f $0 < hoge.js > moge.js
load( ['/path/to/JsDecoder.js'] );
var jsdecoder = new JsDecoder();
var lines = '';
var ln;
while ( ( ln = readline() ) !== null ) {
  lines += ln + "\n";
}
jsdecoder.s = lines;
print( jsdecoder.decode() );
;

• インデントは、2スペース
• '{'は同じ行
