# Tests:
# Included tests (tests/*) are seriously outdated
# Upstream's main test suite (msautotest/*) is not in the release tarball,
# and upstream sets 'export-ignore' for that directory.
#
# The eclasses used normally try to run test suites themselves,
# or skip if nothing was found.
# However, because of the php-ext-* eclass usage, this fails and would
# cause errors running non-existent tests, so we have to restrict here.
