This is a continuation of the profiler deegc and tarlen maintained on SourceForge, which is itself a continuation of the 3EProfiler project created by Michael J Eggertson (which was on www.3eprofiler.net, but that no longer exists).
A DnD group using it decided to hack on it a bit; we'll publish what we do here. We have at least tarlen's blessing for this and appear to have thereby inherited the onerous burden of maintainership ;^>
