Add man page

[markcaudill]

I saw mention of wanting a man page so I took the one from rsync and replaced everything with some of the contents of the readme. I'm not sure what next steps would be. Feel free to disregard this.

You can preview the file by running man runitor.1 from the project root.

Thanks for taking the initiative.

I don't think having the man page in roff is anywhere sustainable. I've done my own share of doing this for OpenBSD man pages, dunno 20 years ago but today these should be written in Markdown or something equally reasonable so it can be converted to whatever presentation format is desired, be it roff for man pages, HTML for online browsing, or PDF for people who like printing things.

If you're up for doing something like this, where we can also CLI help text in the source code and the docs in sync, and rely on a doc converter (Pandoc comes to mind), I'd be happy to collaborate on a PR like that.

I this current form, as a sole developer, I cannot possibly maintain a roff file.

Yeah I completely agree about maintaining roff. My first instinct was to see if I could hook into any current document generation but I didn't see where I could do that.

I'm happy if you close this and as time allows I'll try to see about maybe leveraging go doc or something if you think that's the right direction (I'm not as familiar with the Go ecosystem and idioms).
