Oh, cool. Guess I'll be reconfiguring my animals soon :-)
> But if you want to run some more frequently you'd still be stuck having to manage that yourself. There's actually not
alot of point in doing it that way, though. We don't build unless there have been changes on the branch, unless told
otherwise,so you might as well run frequently and test all the branches - for the most part only HEAD (i.e. master)
willbe built because it gets far more changes than the back branches.
It was something Tom asked for ages ago, so he could see if the
Windows build got broken more promptly. I didn't want multiple
branches running with increased frequency as I run a number of animals
on a single machine with vmware, and a back patched change could cause
a lot of extra work.
