I wanted to have an overview of pisi, which seems to be an interesting package manager in python (for the Pardus linux distrib), and I felt on a small paper formalizing how the dependency resolution is done. http://www.pardus.org.tr/eng/projects/pisi/index.html http://svn.pardus.org.tr/uludag/trunk/pisi/doc/dependency.pdf I found it interesting so wanted to share it with others ;) There are also many neat features : http://www.pardus.org.tr/eng/projects/pisi/PiSi.html
