In one of the company project, we use scons, but some people hate it actually. I think it’s quite decent, the python scripts are clean and simple to read. But the problem is actually the performance.

   There is actually a current debate about the scons performance [1] vs [2]. I don’t know why (some bias) I tend to think [1] is a bit more right, at least the benchmarks are quite convincing.

But the scripts are written in python, what were you expecting?
