 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
