# runant.pl
#
# wrapper script for invoking ant in a platform with Perl installed
# this may include cgi-bin invocation, which is considered somewhat daft.
# (slo: that should be a separate file which can be derived from this
# and returns the XML formatted output)
#
# the code is not totally portable due to classpath and directory splitting
# issues. oops. (NB, use File::Spec::Functions will help and the code is
# structured for the catfile() call, but because of perl version funnies
# the code is not included.
