rpm maintains a database of the installed software, the files installed=
by
each package, and some metainfo on the files. Besides uninstall support, r=
pm
allows you to verify the integrity of the files since it tracks the=20
owner, group, permissions, and a md5 hash of the files. rpm also provides=

for depedency checking and for running pre or post install and uninstall=20
scripts. =20

However, this would require another option to specify the native=20
installer since distutils can't determine whether a linux system is using
rpm or not. I'm leaning towards adding another option to specify whether
the installs are to be made using binary packages or not. This in conjunct=

with the install type should cover the cases. =20

Currently it's not an option. Distutils doesn't record the location of
installed files so there isn't a way to uninstall packages. It's possible
with windows or rpm or debian based systems however. =20
