Before I committed this I wanted to do some reading on man pages to make sure I understand things properly. We are actually going to want to maintain a number of man pages. I first want to point out that we fall into two categories:

1   Executable programs or shell commands
3   Library calls (functions within program libraries)

This is a good start to adding man pages, but if we are to catch up man pages to the current state of the project we are going to want a man page for each of our executables, and each out our libraries.

It would be awesome if you wanted to take ownership of #32!

Thanks for the contribution as always friend!! 👋
