- =head1 NAME
-
- foo, bar - programs to do something
-
- =head1 SYNOPSIS
-
- A short usage summary.
-
- B<foo> { B<this>|B<that> } [ B<-flags> ] [ B<-o> I<option> ] I<argument> [ I<more...> ]
-
- =head1 DESCRIPTION
-
- Long drawn-out discussion of the program. It's a good idea to break this
- up into subsections using "=head2" directives, like these:
-
- =head2 A Sample Subsection
-
- =head2 Yet Another Sample Subsection
-
- References to the foo(1) (or other) manual page should be written normally
- as here; B<pod2man> will usually guess the correct formatting. Use S<L><>
- (e.g. L<foo(SECTION)>) if you need to force this.
-
- Paragraphs are separated by blank lines.
-
- =head1 OPTIONS
-
- Some people make this separate from the description.
-
- The following style is typically used to document options:
-
- =over 8
-
- =item B<this>|B<that>
-
- The user MUST specify either B<this> or B<that> to run the program. The {
- and } braces mean one of the enclosed is required. The bar (|) separates
- exclusive options (i.e. you cannot have both at once).
-
- =item B<-o>
-
- Pass the user-supplied I<option> to B<foo> to change its behaviour. The
- fact that I<option> is underlined or in italics means that the user replaces
- it with a valid value for this option. The [ and ] brackets mean it isn't
- required.
-
- =item I<argument>
-
- The last I<argument> is required, because it is not in brackets.
-
- =item I<more>
-
- means that the user can optionally specify additional arguments at the end.
- The ellipses (...) indicate one or more of this parameter is allowed.
-
- =back
-
- =head1 RETURN VALUE
-
- What the program or function returns if successful.
-
- =head1 ERRORS
-
- Return codes, either exit status or errno settings.
-
- =head1 EXAMPLES
-
- Give some example uses of the program.
-
- =head1 ENVIRONMENT
-
- Environment variables this program might care about.
-
- =head1 FILES
-
- All files used by the program. Typical usage is like this:
-
- =over 8
-
- =item F</usr/man>
-
- default man tree
-
- =item F</usr/man/man*/*.*>
-
- unformatted (nroff source) man pages
-
- =back
-
- =head1 NOTES
-
- Miscellaneous commentary.
-
- =head1 CAVEATS
-
- Things to take special care with, sometimes called WARNINGS.
-
- =head1 DIAGNOSTICS
-
- All the possible error messages the program can print out, what they
- mean, and how to correct them if applicable.
-
- =head1 BUGS
-
- Things that are broken or just don't work quite right.
-
- =head1 RESTRICTIONS
-
- Bugs you don't plan to fix. :-)
