# xbppScan - Simple Xbase++ class scanner.
#
# This is a simple script to run thru a set of Xbase++ sources and locate
# any class definitions. The method used is pretty brain dead and could be a
# lot more elegant. Also, the output format is pretty simple too.
#
# Note that for this script to work you also need csyScan.py in your python
# LIB path.
