POD2MAN(1) POD2MAN(1)
NAME
pod2man - translate embedded Perl pod directives into man pages
SYNOPSIS
pod2man [ --section=manext ] [ --release=relpatch ] [ --center=string ] [
--date=string ] [ --fixed=font ] [ --official ] [ --lax ] inputfile
DESCRIPTION
pod2man converts its input file containing embedded pod directives (see
the perlpod manpage) into nroff source suitable for viewing with nroff(1)
or troff(1) using the man(7) macro set.
Besides the obvious pod conversions, pod2man also takes care of func(),
func(n), and simple variable references like $foo or @bar so you don't
have to use code escapes for them; complex expressions like
$fred{'stuff'} will still need to be escaped, though. 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.
OPTIONS
center Set the centered header to a specific string. The default is
"User Contributed Perl Documentation", unless the --official flag
is given, in which case the default is "Perl Programmers
Reference Guide".
date Set the left-hand footer string to this value. By default, the
modification date of the input file will be used.
fixed The fixed font to use for code refs. Defaults to CW.
official
Set the default header to indicate that this page is of the
standard release in case --center is not given.
release Set the centered footer. By default, this is the current perl
release.
section Set the section for the .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 /usr/local/perl/man/. By default, section 1 will be
used unless the file ends in .pm in which case section 3 will be
selected.

lax Don't complain when required sections aren't present.
Anatomy of a Proper Man Page
For those not sure of the proper layout of a man page, here's an example
of the skeleton of a proper man page. Head of the major headers should
be setout as a =head1 directive, and are historically written in the
rather startling ALL UPPER CASE format, although this is not mandatory.
Minor headers may be included using =head2, and are typically in mixed
case.
NAME Mandatory section; should be a comma-separated list of programs
or functions documented by this podpage, such as:
foo, bar - programs to do something
SYNOPSIS A short usage summary for programs and functions, which may
someday be deemed mandatory.
DESCRIPTION
Long drawn out discussion of the program. It's a good idea to
break this up into subsections using the =head2 directives,
like
=head2 A Sample Subection
=head2 Yet Another Sample Subection
OPTIONS Some people make this separate from the description.
RETURN VALUE
What the program or function returns if successful.
ERRORS Exceptions, return codes, exit stati, and errno settings.
EXAMPLES Give some example uses of the program.
ENVIRONMENT
Envariables this program might care about.
FILES All files used by the program. You should probably use the F<>
for these.
SEE ALSO Other man pages to check out, like man(1), man(7),
makewhatis(8), or catman(8).
NOTES Miscellaneous commentary.
CAVEATS Things to take special care with; sometimes called WARNINGS.

DIAGNOSTICS
All possible messages the program can print out--and what they
mean.
BUGS Things that are broken or just don't work quite right.
RESTRICTIONS
Bugs you don't plan to fix :-)
AUTHOR Who wrote it (or AUTHORS if multiple).
HISTORY Programs derived from other sources sometimes have this, or you
might keep a modification log here.
EXAMPLES
pod2man program > program.1
pod2man some_module.pm > /usr/perl/man/man3/some_module.3
pod2man --section=7 note.pod > note.7
DIAGNOSTICS
The following diagnostics are generated by pod2man. Items marked "(W)"
are non-fatal, whereas the "(F)" errors will cause pod2man to immediately
exit with a non-zero status.
bad option in paragraph %d of %s: ``%s'' should be [%s]<%s>
(W) If you start include an option, you should set it off as bold,
italic, or code.
can't open %s: %s
(F) The input file wasn't available for the given reason.
Improper man page - no dash in NAME header in paragraph %d of %s
(W) The NAME header did not have an isolated dash in it. This is
considered important.
Invalid man page - no NAME line in %s
(F) You did not include a NAME header, which is essential.
roff font should be 1 or 2 chars, not `%s' (F)
(F) The font specified with the --fixed option was not a one- or
two-digit roff font.
%s is missing required section: %s
(W) Required sections include NAME, DESCRIPTION, and if you're using
a section starting with a 3, also a SYNOPSIS. Actually, not having a
NAME is a fatal.
Unknown escape: %s in %s
(W) An unknown HTML entity (probably for an 8-bit character) was
given via a E<> directive. Besides amp, lt, gt, and quot, recognized
entities are Aacute, aacute, Acirc, acirc, AElig, aelig, Agrave,

Eacute, eacute, Ecirc, ecirc, Egrave, egrave, ETH, eth, Euml, euml,
Iacute, iacute, Icirc, icirc, Igrave, igrave, Iuml, iuml, Ntilde,

Otilde, otilde, Ouml, ouml, szlig, THORN, thorn, Uacute, uacute,
Ucirc, ucirc, Ugrave, ugrave, Uuml, uuml, Yacute, yacute, and yuml.
Unmatched =back
(W) You have a =back without a corresponding =over.
Unrecognized pod directive: %s
(W) You specified a pod directive that isn't in the known list of
=head1, =head2, =item, =over, =back, or =cut.
NOTES
If you would like to print out a lot of man page continuously, you
probably want to set the C and D registers to set contiguous page
numbering and even/odd paging, at least on some versions of man(7).
Settting the F register will get you some additional experimental
indexing:
troff -man -rC1 -rD1 -rF1 perl.1 perldata.1 perlsyn.1 ...
The indexing merely outputs messages via .tm for each major page,
section, subsection, item, and any X<> directives.
RESTRICTIONS
None at this time.
BUGS
The =over and =back directives don't really work right. They take
absolute positions instead of offsets, don't nest well, and making people
count is suboptimal in any event.
AUTHORS
Original prototype by Larry Wall, but so massively hacked over by Tom
Christiansen such that Larry probably doesn't recognize it anymore.
