Well, it bisecting using toposort needs manual adjustments. Nevertheless it's still helpful.

Well, it's been couple of years since my graph theory classes, but I still remember something -- so it's clear. ;) As usual, it's a matter of time -- current version is just, more or less, one-day tcl script for particular purpose. Right now I'm considering automation for building and running test. Fire-and-forgot tool, similar to git-bisect run. Well, I will think about graphs, thou. Graphs are fun, you know... ;) Cheers, Ł.
