m9u is a music server, similar to mpd or xmms2. It sits in the background, waiting for commands to be delivered via a 9p file system. m9u embraces the Unix philosophy of doing one thing well. As such, it does not try to catalog or otherwise organize music, but aims for the more humble goal of simply playing it. A side effect of this approach is that m9u is trivially extensible to domains aside from music (for example, an image slideshow).
Phacter is a Python port of facter, a tool included in Puppet. It provides an inventory of your system and, depending on how it is run, will return this data to stdout or as a Python dict. It is the first part of a project that aims to be a Python-based systems administration framework called Speed (ServersOnSpeed).

sqlzma is a patch against lzma and squashfs that makes squashfs support both LZMA compression and ZLIB compression. A squashfs image file that uses LZMA compression has no backward compatibility, but the patched squashfs and its tools can handle the old squashfs image generated by the unpatched squashfs-tools.
