Hi! I'm still missing how can I send a program to my friend, who doesn't have and doesn't want to install ruby. So I need a mechanism to pack things into a single directory, which can run on a windows NT/98/2k or linux. ps: btw python can do it, eg. blender doesn't need python, however it is written in python.
