#
# Opbeat is looking for the best CLI syntax for the `opbeat'  
# command that sends deployment info to the Opbeat API.
#
# Users should be able to specify repositories that the app being deployed
# consists of and their attributes.
# 
# The attributes are "name", "version", "vcs", "rev", "branch", "remote_url".
#
# We are considering these syntaxes:

# Delete Python's compiled *.pyc and __pycache__ files like a pro
# https://gist.github.com/jakubroztocil/7892597

# Usage:
# Delele *.pyc and __pycache__ files recursively in the current directory:
# $ pyc  
# 
# The same, but under /path:
