# ================================================================
# NOTE:
# using this fabfile expects that you have the python utility
# fabric installed locally, ssh access to reamea.com, and your
# ssh public key associated with the account 'mboza@reamea.com'
# ================================================================
# USAGE:
#
# * fab linode background_setup
# install the ubuntu/debian based packages needed for Apache,
# mod_wsgi, etc to support our pinax-based project
#
# * fab linode setup
# establish a python virtual environment in the worker directory
#
# * fab linode deploy
# deploys the contents of your current mercurial repository up
# to soulcraft.com and pushes out the prototype dir into
# /var/www for immediate viewing
#
# * fab linode initialize
# ONLY RUN ONCE FOR THE SITE - initializes a superuser account
# and sets the admin password
