# parameters for the charm. When you run `charm build` it'll pull in the 
# code for the apt layer. There's actually quite a large number of layers
# like layer-apt that you can build upon. They are listed here:
# http://interfaces.juju.solutions/ Each should have a README outlining how
# to use that layer
