I couldn't find a library for this or simple guide to this job (note: especially for manual pages).
I'm not familiar with ROFF, but I assume the
roff crate isn't working for you?
Probably a random side note, but Cargo uses the
mdman rustc crate. According to
Format, it supports plain text as output format, but unfortunately I don't think it supports ROFF as input (only markdown + handlebars templates).
In this case, I think I have to make my own library. I doubt about
roff markdown sections every time when I try to develop a
man alternative in Rust, even with documentation (also it's bit hard to find them because they seem like old documents)
