# This is untested. It makes many assumptions. Understand it, 
# and Cliff's original blog post, before running this recipe on
# your system.

# In order for the post-receive hook to work, the user that runs
# it will need to have a knife configuration file and client on
# the server if running Chef 0.8.x+.
