-=head1 NAME
-
-pod2man - translate embedded Perl pod directives into man pages
-
-=head1 SYNOPSIS
-
-B<pod2man>
-[ B<--section=>I<manext> ]
-[ B<--release=>I<relpatch> ]
-[ B<--center=>I<string> ]
-[ B<--date=>I<string> ]
-[ B<--fixed=>I<font> ]
-[ B<--official> ]
-[ B<--lax> ]
-I<inputfile>
-
-=head1 DESCRIPTION
-
-B<pod2man> converts its input file containing embedded pod directives (see
-L<perlpod>) into nroff source suitable for viewing with nroff(1) or
-troff(1) using the man(7) macro set.
-
-Besides the obvious pod conversions, B<pod2man> also takes care of
-func(), func(n), and simple variable references like $foo or @bar so
-you don't have to use code escapes for them; complex expressions like
-C<$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.
-
-=head1 OPTIONS
-
-=over 8
-
-=item center
-
-Set the centered header to a specific string. The default is
-"User Contributed Perl Documentation", unless the C<--official> flag is
-given, in which case the default is "Perl Programmers Reference Guide".
-
-=item date
-
-Set the left-hand footer string to this value. By default,
-the modification date of the input file will be used.
-
-=item fixed
-
-The fixed font to use for code refs. Defaults to CW.
-
-=item official
-
-Set the default header to indicate that this page is of
-the standard release in case C<--center> is not given.
-
-=item release
-
-Set the centered footer. 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/>. By default, section 1 will be used
-unless the file ends in F<.pm> in which case section 3 will be selected.
-
-=item lax
-
-Don't complain when required sections aren't present.
-
-=back
-
-=head1 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 C<=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 C<=head2>, and are
-typically in mixed case.
-
-=over 10
-
-=item 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
-
-=item SYNOPSIS
-
-A short usage summary for programs and functions, which
-may someday be deemed mandatory.
-
-=item DESCRIPTION
-
-Long drawn out discussion of the program. 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. You should probably use the FE<lt>E<gt>
-for these.
-
-=item SEE ALSO
-
-Other man pages to check out, like man(1), man(7), makewhatis(8), or catman(8).
-
-=item NOTES
-
-Miscellaneous commentary.
-
-=item CAVEATS
-
-Things to take special care with; sometimes called WARNINGS.
-
-=item DIAGNOSTICS
-
-All possible messages the program can print out--and
-what they mean.
-
-=item BUGS
-
-Things that are broken or just don't work quite right.
-
-=item RESTRICTIONS
-
-Bugs you don't plan to fix :-)
-
-=item AUTHOR
-
-Who wrote it (or AUTHORS if multiple).
-
-=item HISTORY
-
-Programs derived from other sources sometimes have this, or
-you might keep a modification log here.
-
-=back
-
-=head1 EXAMPLES
-
- pod2man program > program.1
- pod2man some_module.pm > /usr/perl/man/man3/some_module.3
- pod2man --section=7 note.pod > note.7
-
-=head1 DIAGNOSTICS
-
-The following diagnostics are generated by B<pod2man>. Items
-marked "(W)" are non-fatal, whereas the "(F)" errors will cause
-B<pod2man> to immediately exit with a non-zero status.
-
-=over 4
-
-=item 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.
-
-=item can't open %s: %s
-
-(F) The input file wasn't available for the given reason.
-
-=item 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.
-
-=item Invalid man page - no NAME line in %s
-
-(F) You did not include a NAME header, which is essential.
-
-=item roff font should be 1 or 2 chars, not `%s' (F)
-
-(F) The font specified with the C<--fixed> option was not
-a one- or two-digit roff font.
-
-=item %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.
-
-=item Unknown escape: %s in %s
-
-(W) An unknown HTML entity (probably for an 8-bit character) was given via
-a C<EE<lt>E<gt>> directive. Besides amp, lt, gt, and quot, recognized
-entities are Aacute, aacute, Acirc, acirc, AElig, aelig, Agrave, agrave,
-Aring, aring, Atilde, atilde, Auml, auml, Ccedil, ccedil, Eacute, eacute,
-Ecirc, ecirc, Egrave, egrave, ETH, eth, Euml, euml, Iacute, iacute, Icirc,
-icirc, Igrave, igrave, Iuml, iuml, Ntilde, ntilde, Oacute, oacute, Ocirc,
-ocirc, Ograve, ograve, Oslash, oslash, Otilde, otilde, Ouml, ouml, szlig,
-THORN, thorn, Uacute, uacute, Ucirc, ucirc, Ugrave, ugrave, Uuml, uuml,
-Yacute, yacute, and yuml.
-
-=item Unmatched =back
-
-(W) You have a C<=back> without a corresponding C<=over>.
-
-=item Unrecognized pod directive: %s
-
-(W) You specified a pod directive that isn't in the known list of
-C<=head1>, C<=head2>, C<=item>, C<=over>, C<=back>, or C<=cut>.
-
-
-=back
-
-=head1 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 C<.tm> for each
-major page, section, subsection, item, and any C<XE<lt>E<gt>>
-directives.
-
-
-=head1 RESTRICTIONS
-
-None at this time.
-
-=head1 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.
-
-=head1 AUTHORS
-
-Original prototype by Larry Wall, but so massively hacked over by
-Tom Christiansen such that Larry probably doesn't recognize it anymore.
