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>. =head1 SEE ALSO L<Pod::Simple::RTF>, L<Pod::Simple>, L<Pod::Perldoc> =head1 COPYRIGHT AND DISCLAIMERS Copyright (c) 2002 Sean M.
