There seems to be quite a bit of cargo-cult/copy-paste of the mdoc(7)
markup when it comes to writing manual pages. Some time ago I tried
to write a tutorial but kinda hit a writer's block. Then I tried to
just do a jumbo^Hled man page(s) to have a single convenient source
for casual users to steal from, but, again, got sidetracked with other
things.
I thought to commit these somewhere to /usr/share (examples,
probably), but at the current rate I'm not sure when I'll get around
to it. Since unfinished/imperfect is still better than nothing, I put
the sources here:
