+
+=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
+

+=head1 NAME
+
+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.

+=head1 SYNOPSIS

+
+=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::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>.

+
+This is a "plug-in" class that allows Perldoc to use

+This module may change to use a different text formatter class in the
