I thought people here might be interested in my Releasy gem. It makes
using Ocra simpler, as well as extending it significantly (Can
build .exe on any platform) and mixing it up with a system to make OS
X executables too!
Releasy
======
Releasy automates the release of Ruby applications for non-Ruby users,
such as games or GUI applications.
By configuring a Releasy::Project in your application's Rakefile,
Releasy can generate Rake tasks for use when there is a need to build,
package (archive) and/or deploy a new version of the application.
