Subject: Create a PORTAGE_IUSE variable containing an egrep pattern
X-Git-Tag: v2.2_pre1~167
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=11e10ec824550554651409c089ea1095449cb672;p=portage.git

Create a PORTAGE_IUSE variable containing an egrep pattern
for use by the QA check that's built into useq(). This allows
the IUSE logic for this check to be isolated in the python
code.
