Ok, more specifically, troff using the mm macros to HTML. This is another from my "rusty scripts" collection which was written for a specific task long ago. In this case, we were converting some internal documentation from troff using the mm macros into HTML. troff is a very sophisticated system so doing this right would be a lot of work. But, writing something to get rid of 90% of the grunt work of conversion is pretty easy. Paul Dunne did one for the ms macro set which you can find here but mm is different.
