RubyScript2Exe 0.5.0. just released. RubyScript2Exe transforms your Ruby application into a standalone, compressed Windows, Linux or Mac OS X (Darwin) executable. You can look at it as a "compiler". Not in the sense of a source-code-to-byte-code compiler, but as a "collector", for it collects all necessary files to run your script on an other machine: the Ruby script, the Ruby interpreter and the Ruby runtime library (stripped down for this script).
