runant.py
This script is a translation of the runant.pl written by Steve Loughran.
It runs ant with/out arguments, it should be quite portable (thanks to
the python os library)
This script has been tested with Python2.0/Win2K
created: 2001-04-11
author: Pierre Dittgen pierre.dittgen@criltelecom.com
Assumptions:
- the "java" executable/script is on the command path
- ANT_HOME has been set
