#!/usr/bin/env python
# killpcgi.py - kill a running pcgi process
# Copyright(c) 1998, Jeff Bauer, All rights reserved.
# killpcgi is a convenience script to kill a running
# pcgi process, provided that it is running on a
# Unix system. You pass it the path of the pcgi info
# file, and killpcgi will kill the running process and
# remove the socket/pid files.
#
# killpcgi has been built at the request of several users,
# but you may want to first examine the script and modify it
# to suit your environment.
#
# Bugs: skimpy error handling
# 0.3a minor win32 exception caught
# 0.2a Added support for NT - 8/8/98
# 0.1a Initial version
__version__ = "0.3a"
