In the name of saving energy I've changed the architecture of the machine that produces the nightly builds from x86_64 to armel.
If you have any problems with builds produced after 2010-01-04 please let me know and I'll investigate it.
If someone can come up with some magic to detect whether anything has changed in CVS I'll sort out the build so that it only fires if something has changed.
That's probably the difficult way to do it. There must be a way with the correct incantation of cvs log - perhaps I'll look at cruisecontrol and see what it does.
