# This is a ruby script which can be configured with svn post-commit Hook.
# Once configured, it will send commit notification by email, which will
# contain log message, files added/updated and svn diff.
#
#
# This script is written by Akhil Bansal(http://webonrails.com)
# It worked fine for me. Use this script at your own risk, if 
# your computer explode, it will not be my fault ;-)
