Describe the solution you'd like
The current man page for SlackJP (slackjp.1) is written in TROFF. To maintain appropriate man page formatting, a new solution for writing these TROFF/GROFF pages is preferred.

Currently, the man page is writing in a VSCode with minimal syntax highlighting.

Describe alternatives you've considered
No promising alternative solutions other than "keep doing what is already done" has been thought up. Solution(s) should be explored and investigated.
