Orc has moved to its new home at code.entropywave.com. The git repository was previously hosted from my home directory at freedesktop.org, and there was no main web page to direct people to. That will be fixed now that it has a real web site. This move has been planned for some time, but the recent power outage and subsequent meltdown of the filesystem at freedesktop.org that contained the repository triggered the action.
The Git clone URI for Orc is now git://code.entropywave.com/git/orc.git
