+#
+# 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.

+# - ANT_HOME has been set
+# - target platform uses ":" as classpath separator or perl indicates it is dos/win32
+# - target platform uses "/" as directory separator.
+
+#be fussy about variables

+#platform specifics (disabled)
+#use File::Spec::Functions;
