103 Pod::Text::Color is a simple subclass of Pod::Text that highlights output
104 text using ANSI color escape sequences. Apart from the color, it in all
105 ways functions like Pod::Text. See L<Pod::Text> for details and available
108 Term::ANSIColor is used to get colors and therefore must be installed to use
113 This is just a basic proof of concept. It should be seriously expanded to
114 support configurable coloration via options passed to the constructor, and
115 B<pod2text> should be taught about those.
