Quick glance tells me that Packman is a project not connected with SUSE--Why not use the SUSE package manager?
This is straying from the topic, but I am finding that the #1 discriminator among distros is the package management system. Right now, I would rank a few of them this way:
#1 APT/Synaptic (Debian, Ubuntu, Mepis, etc)
#2 Pacman (Arch Linux)
#3 YUM/RPM (Fedora)
~#5 or 6 YAST (SUSE and others)
