Distributing Ruby/Python desktop apps
For python, we have things like py2exe, py2app, freeze.
I only want a runnable application; it can even not be an exe or an app. I just want to distribute the ruby/python interpreter with all the libraries and my application to the user. It's more like an embedded version of application.
Is there any tools like this for ruby (and for python, maybe)? It's better if it is cross-platform, including OSX, windows and linux.
