#
# watchXsiservers is a little script that checks for the presence
# of network locations, and sends an error in case the target path
# is no longer inaccessible.
# This is meant to watch over frequently accessed critical
# shared ressources.
#
#
# Installation
# Put file into C:\PythonXX\Lib
# Remove "_public" from file name
# The script requires the easygui.py file to be installed
# in the Lib directory.
#
#
# Usage
# Launch Python interpreter (ideally command line)
# Run:
# import watchXsiservers
#
# The script will run indefinitely until the command line
# shell is closed, the script stopped, or the servers it
# watches are no longer available.
#
# This script is written to watch two servers.
# Feel free to modify it for your needs.
