# Test::Harness produces cleaner output than automake's default test

# set TESTS to the full list of tests, which is good because automake
# doesn't support wildcards, and so it would be too easy to forget to
# add a new one to the list.
#
# Note that automake's `check' rule cannot be overridden
# for some weird reason:
#
#   http://thread.gmane.org/gmane.comp.sysutils.automake.general/13040/focus=13041
#
# so we override check-TESTS instead which is where the real work is
# done anyway.  Unfortunately this produces a warning with the -Wall
# option to AM_INIT_AUTOMAKE which has to be silenced via
# -Wno-override.
