remv0r

When invoked with parameter "new" (which should be the first step), it creates a file "pkglist" with a list of all packages that where neither pulled by another package nor listed in the pkglist file (if its exists). Just delete every line from this file that you dont actually wont to have installed.
Then call remv0r with the parameter "do". All packages that are neither a dependency to something nor listed in pkglist will be removed, and either so all packages that where dependend only by those removed.
Note: Sometimes it might be needed to run it again, even when no new packages are shown. Hey, dont complain, its just a quick hack.
