Now we even have two choices.  Didn't know that there are two build
systems although A-A-P rings some bells.

I guess a GUI is not of primary importance to us but i am not
sure if the number compilers and languages is important.  We'll
try to go with subversion but a-a-p (what a name, btw :-) could
certainly be adapted to it.

Nice website, especially your tools collection!  And a-a-p also
seems to have an advantage regarding documentation. 

I give both projects a closer look although i probably like
to work with SCons first because i know it somewhat and don't 
care about makefile syntax too much.  But this also depends on the
people attending the Sprint and their preferences. 

Thanks for the pointers!
