Where should I install data files for the library I wrote? They are
connected with .rb files, so they should stay in the same directory, but
setup.rb does not install anything but .rb files from lib/ subdirectory.
The default data dir (/usr/share on my Gentoo Linux) does not seems
appropiate, too (I want my library to be installed in one place). 

Maybe there should be something like java .jar files, which can contain
not only java class files, but also the resource files (corrent me if
I'm wrong)?
