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).
