#usage To find the regression range for a bug, supply mozregression with the date of the last known good nightly and the date of a bad nightly (optional):
mozregression --good=2010-03-16 --bad=2010-09-08
This will download and run several nightly builds on new profiles and narrow down the range. After checking a few nightlies, you'll get the regression range which looks something like this:
Last good nightly: 2010-09-08 First bad nightly: 2010-09-09
