masq is a command line utility that allows the user to edit any flat file in any format using the format of their choosing.
masq_yaml is a plugin providing YAML formatting options for the masq utility.
masq_yaml requires just masq and PyYAML. Built in Python 2.7. Not tested (yet) in 2.6 or 3.x lines, but I'm not opposed to the idea.
One day, pip install masq_yaml will work. I promise.
