# Interesting tasks are:
#
# * purge: Remove everything but the application and the git repository.
# * purge_conf: Purge configurations.
# * purge_dep: Uninstall all packages.
# * deploy: Deploy the flask application to "/home/flask/*project_name*".
# * update: Update the app from the remote repository.
# * update_from_local(local_path): Update application from local sources.
#
# Version 0.2.0
#
# * Made all directories dynamically configurable in the beginning.
#
# Version 0.1.2
