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