# 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.

# Assumptions:

#

# - the "java" executable/script is on the command path

# - 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

use strict;

#platform specifics (disabled)

#use File::Spec::Functions;

#turn warnings on during dev; generates a few spurious uninitialised var access warnings

#use warnings;

#and set $debug to 1 to turn on trace info
