bMotion nightly archives are generated every night from the SVN repository.

This means they might be broken!

Usually SVN works ok, but sometimes not perfectly. My development bot runs SVN
so it's generally safe to run it. Be wary of automagically grabbing
the nightly and blindly upgrading your bot, in case something major changes.
