Feature: author manpage in markdown

[orndorffgrant]

Please describe the scenario where the new feature would be useful

3082

Describe the solution you'd like

authoring our manpage in markdown will make it easier to update, because the dev team is familiar with markdown syntax

we may be able to do this with pandoc?

Something like this pandoc --standalone --to man pro.1.md -o pro.1
