How to create a man page?

[brian.barto at spectrum-health.org]

Hi all. I am writing a program with hopes to submit it for inclusion to the
ports collection. My last step is to include a man page for my program. Man
pages look to be some sort of markup language. What is the standard way to
create a man page? Is there some sort of wysiwyg or some other program that
makes them easy to create?
 
Thanks,
Brian
