DESCRIPTION
pod2man is a wrapper script around the Pod::Man module, using it to generate *roff input from
POD source. The resulting *roff code is suitable for display on a terminal using nroff(1),
normally via man(1), or printing using troff(1).

By default (on non-EBCDIC systems), pod2man outputs UTF-8 manual pages. Its output should
work with the man program on systems that use groff (most Linux distributions) or mandoc
(most BSD variants), but may result in mangled output on older UNIX systems. To choose a
different, possibly more backward-compatible output mangling on such systems, use
"--encoding=roff" (the default in earlier Pod::Man versions). See the --encoding option and
"ENCODING" in Pod::Man for more details.

input is the file to read for POD source (the POD can be embedded in code). If input isn't
given, it defaults to "STDIN". output, if given, is the file to which to write the formatted
output. If output isn't given, the formatted output is written to "STDOUT". Several POD
files can be processed in the same pod2man invocation (saving module load and compile times)
by providing multiple pairs of input and output files on the command line.

--section, --release, --center, --date, and --official can be used to set the headers and
footers to use. If not given, Pod::Man will assume various defaults. See below for details.

OPTIONS
Each option is annotated with the version of podlators in which that option was added with
its current meaning.

-c string, --center=string
[1.00] Sets the centered page header for the ".TH" macro to string. The default is "User
Contributed Perl Documentation", but also see --official below.

-d string, --date=string
[4.00] Set the left-hand footer string for the ".TH" macro to string. By default, the
first of POD_MAN_DATE, SOURCE_DATE_EPOCH, the modification date of the input file, or the
current date (if input comes from "STDIN") will be used, and the date will be in UTC.
See "CLASS METHODS" in Pod::Man for more details.

-e encoding, --encoding=encoding
[5.00] Specifies the encoding of the output. encoding must be an encoding recognized by
the Encode module (see Encode::Supported). The default on non-EBCDIC systems is UTF-8.

If the output contains characters that cannot be represented in this encoding, that is an
error that will be reported as configured by the --errors option. If error handling is
other than "die", the unrepresentable character will be replaced with the Encode
substitution character (normally "?").

If the "encoding" option is set to the special value "groff" (the default on EBCDIC
systems), or if the Encode module is not available and the encoding is set to anything
other than "roff" (see below), Pod::Man will translate all non-ASCII characters to
"\[uNNNN]" Unicode escapes. These are not traditionally part of the *roff language, but
are supported by groff and mandoc and thus by the majority of manual page processors in
use today.

If encoding is set to the special value "roff", pod2man will do its historic
transformation of (some) ISO 8859-1 characters into *roff escapes that may be adequate in
troff and may be readable (if ugly) in nroff. This was the default behavior of versions
of pod2man before 5.00. With this encoding, all other non-ASCII characters will be
replaced with "X". It may be required for very old troff and nroff implementations that
do not support UTF-8, but its representation of any non-ASCII character is very poor and
often specific to European languages. Its use is discouraged.

WARNING: The input encoding of the POD source is independent from the output encoding,
and setting this option does not affect the interpretation of the POD input. Unless your
POD source is US-ASCII, its encoding should be declared with the "=encoding" command in
the source. If this is not done, Pod::Simple will will attempt to guess the encoding and
may be successful if it's Latin-1 or UTF-8, but it will produce warnings. See perlpod(1)
for more information.

--errors=style
[2.5.0] Set the error handling style. "die" says to throw an exception on any POD
formatting error. "stderr" says to report errors on standard error, but not to throw an
exception. "pod" says to include a POD ERRORS section in the resulting documentation
summarizing the errors. "none" ignores POD errors entirely, as much as possible.

The default is "die".

--fixed=font
[1.0] The fixed-width font to use for verbatim text and code. Defaults to "CW". Some
systems may want "CR" instead. Only matters for troff output.

--fixedbold=font
[1.0] Bold version of the fixed-width font. Defaults to "CB". Only matters for troff
output.

--fixeditalic=font
[1.0] Italic version of the fixed-width font (something of a misnomer, since most fixed-
width fonts only have an oblique version, not an italic version). Defaults to "CI".
Only matters for troff output.

--fixedbolditalic=font
[1.0] Bold italic (in theory, probably oblique in practice) version of the fixed-width
font. Pod::Man doesn't assume you have this, and defaults to "CB". Some systems (such
as Solaris) have this font available as "CX". Only matters for troff output.

--guesswork=rule[,rule...]
[5.00] By default, pod2man applies some default formatting rules based on guesswork and
regular expressions that are intended to make writing Perl documentation easier and
require less explicit markup. These rules may not always be appropriate, particularly
for documentation that isn't about Perl. This option allows turning all or some of it
off.

The special rule "all" enables all guesswork. This is also the default for backward
compatibility reasons. The special rule "none" disables all guesswork. Otherwise, the
value of this option should be a comma-separated list of one or more of the following
keywords:

functions
Convert function references like foo() to bold even if they have no markup. The
function name accepts valid Perl characters for function names (including ":"), and
the trailing parentheses must be present and empty.

manref
Make the first part (before the parentheses) of man page references like foo(1) bold
even if they have no markup. The section must be a single number optionally followed
by lowercase letters.

quoting
If no guesswork is enabled, any text enclosed in C<> is surrounded by double quotes
in nroff (terminal) output unless the contents are already quoted. When this
guesswork is enabled, quote marks will also be suppressed for Perl variables,
function names, function calls, numbers, and hex constants.

variables
Convert Perl variable names to a fixed-width font even if they have no markup. This
transformation will only be apparent in troff output, or some other output format
(unlike nroff terminal output) that supports fixed-width fonts.

Any unknown guesswork name is silently ignored (for potential future compatibility), so
be careful about spelling.

-h, --help
[1.00] Print out usage information.

-l, --lax
[1.00] No longer used. pod2man used to check its input for validity as a manual page,
but this should now be done by podchecker(1) instead. Accepted for backward
compatibility; this option no longer does anything.

--language=language
[5.00] Add commands telling groff that the input file is in the given language. The
value of this setting must be a language abbreviation for which groff provides
supplemental configuration, such as "ja" (for Japanese) or "zh" (for Chinese).

This adds:

.mso <language>.tmac
.hla <language>

to the start of the file, which configure correct line breaking for the specified
language. Without these commands, groff may not know how to add proper line breaks for
Chinese and Japanese text if the man page is installed into the normal man page
directory, such as /usr/share/man.

On many systems, this will be done automatically if the man page is installed into a
language-specific man page directory, such as /usr/share/man/zh_CN. In that case, this
option is not required.

Unfortunately, the commands added with this option are specific to groff and will not
work with other troff and nroff implementations.

--lquote=quote
--rquote=quote
[4.08] Sets the quote marks used to surround C<> text. --lquote sets the left quote mark
and --rquote sets the right quote mark. Either may also be set to the special value
"none", in which case no quote mark is added on that side of C<> text (but the font is
still changed for troff output).

Also see the --quotes option, which can be used to set both quotes at once. If both
--quotes and one of the other options is set, --lquote or --rquote overrides --quotes.

-n name, --name=name
[4.08] Set the name of the manual page for the ".TH" macro to name. Without this option,
the manual name is set to the uppercased base name of the file being converted unless the
manual section is 3, in which case the path is parsed to see if it is a Perl module path.
If it is, a path like ".../lib/Pod/Man.pm" is converted into a name like "Pod::Man".
This option, if given, overrides any automatic determination of the name.

Although one does not have to follow this convention, be aware that the convention for
UNIX manual pages is for the title to be in all-uppercase, even if the command isn't.
(Perl modules traditionally use mixed case for the manual page title, however.)

This option is probably not useful when converting multiple POD files at once.

When converting POD source from standard input, the name will be set to "STDIN" if this
option is not provided. Providing this option is strongly recommended to set a
meaningful manual page name.

--nourls
[2.5.0] Normally, L<> formatting codes with a URL but anchor text are formatted to show
both the anchor text and the URL. In other words:

L<foo|http://example.com/>

is formatted as:

foo <http://example.com/>

This flag, if given, suppresses the URL when anchor text is given, so this example would
be formatted as just "foo". This can produce less cluttered output in cases where the
URLs are not particularly important.

-o, --official
[1.00] Set the default header to indicate that this page is part of the standard Perl
release, if --center is not also given.

-q quotes, --quotes=quotes
[4.00] Sets the quote marks used to surround C<> text to quotes. If quotes is a single
character, it is used as both the left and right quote. Otherwise, it is split in half,
and the first half of the string is used as the left quote and the second is used as the
right quote.

quotes may also be set to the special value "none", in which case no quote marks are
added around C<> text (but the font is still changed for troff output).

Also see the --lquote and --rquote options, which can be used to set the left and right
quotes independently. If both --quotes and one of the other options is set, --lquote or
--rquote overrides --quotes.

-r version, --release=version
[1.00] Set the centered footer for the ".TH" macro to version. By default, this is set
to the version of Perl you run pod2man under. Setting this to the empty string will
cause some *roff implementations to use the system default value.

Note that some system "an" macro sets assume that the centered footer will be a
modification date and will prepend something like "Last modified: ". If this is the case
for your target system, you may want to set --release to the last modified date and
--date to the version number.

-s string, --section=string
[1.00] Set the section for the ".TH" macro. The standard section numbering convention is
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. There is a lot of variation here, however; some systems (like Solaris) use 4
for file formats, 5 for miscellaneous information, and 7 for devices. Still others use
1m instead of 8, or some mix of both. About the only section numbers that are reliably
consistent are 1, 2, and 3.

By default, section 1 will be used unless the file ends in ".pm", in which case section 3
will be selected.

--stderr
[2.1.3] By default, pod2man dies if any errors are detected in the POD input. If
--stderr is given and no --errors flag is present, errors are sent to standard error, but
pod2man does not abort. This is equivalent to "--errors=stderr" and is supported for
backward compatibility.

-u, --utf8
[2.1.0] This option used to tell pod2man to produce UTF-8 output. Since this is now the
default as of version 5.00, it is ignored and does nothing.

-v, --verbose
[1.11] Print out the name of each output file as it is being generated.

EXIT STATUS
As long as all documents processed result in some output, even if that output includes errata
(a "POD ERRORS" section generated with "--errors=pod"), pod2man will exit with status 0. If
any of the documents being processed do not result in an output document, pod2man will exit
with status 1. If there are syntax errors in a POD document being processed and the error
handling style is set to the default of "die", pod2man will abort immediately with exit
status 255.

DIAGNOSTICS
If pod2man fails with errors, see Pod::Man and Pod::Simple for information about what those
errors might mean.

EXAMPLES
pod2man program > program.1
pod2man SomeModule.pm /usr/perl/man/man3/SomeModule.3
pod2man --section=7 note.pod > note.7

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).

troff -man -rC1 -rD1 perl.1 perldata.1 perlsyn.1 ...

To get index entries on "STDERR", turn on the F register, as in:

troff -man -rF1 perl.1

The indexing merely outputs messages via ".tm" for each major page, section, subsection,
item, and any "X<>" directives.
