# Gather files for installing into two lists:

# Makefile has a very small matching, so we have to go this long way.

# Start with all test related files:
ALLFILES = $(wildcard [0-9]??*)

# handle wildcarded multi-suffix matching. Hence we separate the

# Strip suffix to get matching tests. We want to strip from the

# operative for that. So:
#
# Hack: strip the multiple segments after .out with repeated basename calls.

# finally, select the test files by filtering against against the
# stripped output files and sort them to remove duplicates.
