Create manpages

As discussed in the 2022-02-02 meeting minutes, manpages are a desirable usability improvement for these tools. While Python's argparse package automatically provides useful --help output, it does not provide man pages.

In addition to executables, configurations should also contain section 5 manpages. This may require coordination with #27 (closed).

Find a method of creating/maintaining manpages that gives maximum maintainability/least effort.
