Subject: tests: add a --help option to make runtest more friendly
X-Git-Tag: v2.2.0_alpha65~13
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=0e32e6f3b950b6ca05724491cde8c9d04817d670;p=portage.git

tests: add a --help option to make runtest more friendly

At the moment, trying to do `./runtests.h -h` just produces an ugly and
indecipherable traceback.  Make it a bit more friendly.
