Other nagging little roffish things that it catches include translating the minus in something like foo-bar, making a long dash--like this--into a real em dash, fixing up "paired quotes", putting a little space after the parens in something like func(), making C++ and PI look right, making double underbars have a little tiny space between them, making ALLCAPS a teeny bit smaller in troff(1), and escaping backslashes so you don't have to.</p> <h1 id="OPTIONS"><a class="permalink" href="#OPTIONS">#</a>OPTIONS</h1> <dl> <dt id="center"><a class="permalink" href="#center">#</a>center</dt> <dd> <p>Set the centered header to a specific string.

This works best if you put your Perl man pages in a separate tree, like <i>/usr/local/perl/man/</i>.
