Interesting approach. I am currently doing something small for POSIX
only but would like to port it to windows eventually.

But back to my initial question. I a more interested in how people
package lua programs so that they could be installed in a portable
way. Not necessary shipping their own lua interpreter but figure out
whats installed on the system (lua, luajit, picking a suitable
version) figure out where the scripts and other resources/config files
need to be installed, maybe install rocks dependencies and so on. Of
course one could hack Makefiles or other build systems ('make install')
to do such or build packages for each target (.deb, .rpm, ...). I am
just wondering if there is a more lua'ish portable way to deploy lua
programs.
