I have two reasons, why I would argue against splitting the directories:

- Our bin/rivet-mkanalysis script isn't able to put the analysis skeleton 
into the correct directory anymore now (using the --srcroot option).
- Machines have more and more cores now, making the "make -j" option quite 
useful (especially if you use distcc ;)). So having fewer source files in 
one directory is slowing down the build unnecessarily, because make won't 
be able to "multithread" across directories.

Ah, cool. I didn't know that. That's very good then.

Thanks,
