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. - -=head1 OPTIONS - -=over 8 - -=item center - -Set the centered header to a specific string.

By default, this is the current -perl release. - -=item section - -Set the section for the C<.TH> macro. The standard conventions on -sections are to use 1 for user commands, 2 for system calls, 3 for -functions, 4 for devices, 5 for file formats, 6 for games, 7 for -miscellaneous information, and 8 for administrator commands. This works -best if you put your Perl man pages in a separate tree, like -F</usr/local/perl/man/>.

It's a good idea to break this -up into subsections using the C<=head2> directives, like - - =head2 A Sample Subection - - =head2 Yet Another Sample Subection - -=item OPTIONS - -Some people make this separate from the description. - -=item RETURN VALUE - -What the program or function returns if successful. - -=item ERRORS - -Exceptions, return codes, exit stati, and errno settings. - -=item EXAMPLES - -Give some example uses of the program. - -=item ENVIRONMENT - -Envariables this program might care about. - -=item FILES - -All files used by the program.
