not sure if it helps at all, but I'm using this locally:


prints cmdline of tests split up by result, (ie. with single src to
./piglit-summary.py it will just print cmdlines split up by category
of pass/fail/crash/etc, with two srcs it will print pass->fail,
crash->pass, etc)..

I typically use it when I'm making some change in driver to just
cut/paste cmdlines for pass->fail or pass->crash into a script to
re-run a subset of tests while I'm debugging whatever it is that I'm
working on at the time, to avoid full piglit runs or time-consuming
running of regressed tests one by one as I debug.

It was suggested to integrate this w/ piglit-print-commands.py
instead, which seems pretty sensible but I haven't gotten around to
