# Kind of a little bit bastardized automakefile ... This is the
# temporary glue to hold it all together; once our needs change or we
# need something more advanced, we'll implement it.
#
# So far, I understand Make is not the best language, but I felt lazy
# today and wanted to use the default rules of automake [did I alredy
# mentioned I am bastardizing it?].
#
# Ok, I don't use Automake any more
#
# Added patch from dank REMOVE-THIS AT kegel DOT com

# Added tests timeout from Sebastien Decugis (http://nptl.bullopensource.org) 
# Expiration delay is 240 seconds

# The following value is the shell return value of a timedout application.
# with the bash shell, the ret val of a killed application is 128 + signum
# and under Linux, SIGALRM=14, so we have (Linux+bash) 142.
