Pod::Perldoc::BaseTo - Base for Pod::Perldoc formatters
=head1 SYNOPSIS
package Pod::Perldoc::ToMyFormat;
use parent qw( Pod::Perldoc::BaseTo );
...
=head1 DESCRIPTION
This package is meant as a base of Pod::Perldoc formatters,
like L<Pod::Perldoc::ToText>, L<Pod::Perldoc::ToMan>, etc.
It provides default implementations for the methods
is_pageable
write_with_binmode
output_extension
_perldoc_elem
The concrete formatter must implement
new
parse_from_file

Pod::Perldoc::GetOptsOO - Customized option parser for Pod::Perldoc
=head1 SYNOPSIS
use Pod::Perldoc::GetOptsOO ();
Pod::Perldoc::GetOptsOO::getopts( $obj, \@args, $truth )
or die "wrong usage";
=head1 DESCRIPTION
Implements a customized option parser used for
L<Pod::Perldoc>.
Rather like Getopt::Std's getopts:
=over
=item Call Pod::Perldoc::GetOptsOO::getopts($object, \@ARGV, $truth)
=item Given -n, if there's a opt_n_with, it'll call $object->opt_n_with( ARGUMENT )
(e.g., "-n foo" => $object->opt_n_with('foo'). Ditto "-nfoo")
=item Otherwise (given -n) if there's an opt_n, we'll call it $object->opt_n($truth)
(Truth defaults to 1)
=item Otherwise we try calling $object->handle_unknown_option('n')
(and we increment the error count by the return value of it)
=item If there's no handle_unknown_option, then we just warn, and then increment
the error counter
=back
The return value of Pod::Perldoc::GetOptsOO::getopts is true if no errors,
otherwise it's false.

Pod::Perldoc::ToANSI - render Pod with ANSI color escapes
=head1 SYNOPSIS
perldoc -o ansi Some::Modulename
=head1 DESCRIPTION
This is a "plug-in" class that allows Perldoc to use
Pod::Text as a formatter class.
It supports the following options, which are explained in
L<Pod::Text>: alt, indent, loose, quotes, sentence, width
For example:
perldoc -o term -w indent:5 Some::Modulename
=head1 CAVEAT
This module may change to use a different text formatter class in the
future, and this may change what options are supported.

Pod::Perldoc::ToChecker - let Perldoc check Pod for errors
=head1 SYNOPSIS
% perldoc -o checker SomeFile.pod
No Pod errors in SomeFile.pod
(or an error report)
=head1 DESCRIPTION
This is a "plug-in" class that allows Perldoc to use
Pod::Simple::Checker as a "formatter" class (or if that is
not available, then Pod::Checker), to check for errors in a given
Pod file.
This is actually a Pod::Simple::Checker (or Pod::Checker) subclass, and
inherits all its options.

Pod::Perldoc::ToMan - let Perldoc render Pod as man pages
=head1 SYNOPSIS
perldoc -o man Some::Modulename
=head1 DESCRIPTION
This is a "plug-in" class that allows Perldoc to use
Pod::Man and C<groff> for reading Pod pages.
The following options are supported: center, date, fixed, fixedbold,
fixeditalic, fixedbolditalic, quotes, release, section
(Those options are explained in L<Pod::Man>.)
For example:
perldoc -o man -w center:Pod Some::Modulename
=head1 CAVEAT
This module may change to use a different pod-to-nroff formatter class
in the future, and this may change what options are supported.

Pod::Perldoc::ToRtf - let Perldoc render Pod as RTF
=head1 SYNOPSIS
perldoc -o rtf Some::Modulename
=head1 DESCRIPTION
This is a "plug-in" class that allows Perldoc to use
Pod::Simple::RTF as a formatter class.
This is actually a Pod::Simple::RTF subclass, and inherits
all its options.
You have to have Pod::Simple::RTF installed (from the Pod::Simple dist),
or this module won't work.
If Perldoc is running under MSWin and uses this class as a formatter,
the output will be opened with F<write.exe> or whatever program is
specified in the environment variable C<RTFREADER>. For example, to
specify that RTF files should be opened the same as they are when you
double-click them, you would do C<set RTFREADER=start.exe> in your
F<autoexec.bat>.
Handy tip: put C<set PERLDOC=-ortf> in your F<autoexec.bat>
and that will set this class as the default formatter to run when
you do C<perldoc whatever>.

Pod::Perldoc::ToTerm - render Pod with terminal escapes
=head1 SYNOPSIS
perldoc -o term Some::Modulename
=head1 DESCRIPTION
This is a "plug-in" class that allows Perldoc to use
Pod::Text as a formatter class.
It supports the following options, which are explained in
L<Pod::Text>: alt, indent, loose, quotes, sentence, width
For example:
perldoc -o term -w indent:5 Some::Modulename
=head1 PAGER FORMATTING
Depending on the platform, and because this class emits terminal escapes it
will attempt to set the C<-R> flag on your pager by injecting the flag into
your environment variable for C<less> or C<more>.
On Windows and DOS, this class will not modify any environment variables.
=head1 CAVEAT
This module may change to use a different text formatter class in the
future, and this may change what options are supported.
