[MacRuby-devel] Launch an app from the command line

[Laurent Sansonetti]

Hi Corey,

As some already figured it out, you need to create an application bundle (.app) around your MacRuby script (with an Info.plist file, and so on), then run it from the command-line. 

macrubyc can be used to compile your script into a binary executable, but you still need to wrap it inside a .app bundle in order to get your app running as a regular Cocoa app.

HTH,
Laurent
