Subject: tests: add some self-documentation to tests
X-Git-Tag: v0.9.12-rc2~8
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=75d155ec26fd2d6f4f95c3238b44309dca6caf34;p=thirdparty%2Flibvirt.git

tests: add some self-documentation to tests

Alon tried './qemuxml2argvtest --help' to figure out a test failure,
but it didn't help.  The information is in HACKING, but it doesn't
hurt to make the tests also provide their own help.
