Hmm, I'll check that out. Thanks for the heads up!

All --help documentation is generated from the relevant function's docstrings. Other than the actual RST docs, there's only a single place to change. Does Novatools have RST docs that are auto-generated from the decorators somehow? Is the --help output for Novatools only the function signature (because there's a lot more to the help output in bin/glance, including example usage...)?
