  # 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
