+=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.

+
+=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.
