# This is an example of how to write your own harness using 
# Test::Harness::Straps.  It duplicates most of the features of 
# Test::Harness.
#
# It uses an undocumented, experimental
# callback interface.  If you like it, don't like it, would like
# to see it become non-experimental, etc... discuss on perl-qa@perl.org
