From my understanding, uptodate is for Red Hats's .rpm and apt-get is
for Debian's .deb packages, and Slackware uses the old .tar.gz/.tgz type
of packages. Not really interchangeable, although, the .tar.gz/.tgz
packages could be called universal if you don't mind the
./configure>./make>./make install routine that goes along with it. There
is a tool called Alien that is used to install .rpm packages on a .deb
based distro and vice versa.
