Thanks for applying - and for fixing the "whole" typo ;)

Yeah, RHEL/CentOS was likely the big missing gap at the script. With time,
people may end adding other distros there too. As most distros either
use .deb or .rpm packaging[1], I suspect it shouldn't be hard to add support
for them when needed, as they'll end by either use the existing logic,
or require a close enough logic.

[1] Well, last time I checked, Slackware still use tarballs. Slackware
was the first distro I used, back on Kernel 1.0 days. If I ever become 
nostalgic enough, I might eventually write a patch for it some day.

Thanks,
Mauro
