Add plugin logic into the command line

From John Stoffel:

I'd love to see expanded skeletons, or a way for Plugins to add
themselves into a skeleton so that you can more easily start
using/playing with an extension in the manner the Author of the plugin
expects it to be used.

Think of it as documentation by example, with test cases too ideally.

Now how to make this work when you have *lots* of plugins all stomping
all over each other, I don't know.  It's just a thought.

I had written code that does something similar to this at the Dancer Conference. I need to find it and push a sample branch.

No files, tests, or concrete command entry point are named. Start by locating the command-line plugin and skeleton logic, then look for the sample branch the issue author mentioned; the desired behavior and handling of multiple plugins need to be defined before implementation.
