I love comics, and so does all other people on my private Wiki. I like to have a new comic every day.

The plugin includes the same functionality as the dilbert-plugin and the garfield-plugin. Also the plugin is extended with two new comics. Check the (static) examples below.

Copy into webcomics/syntax.php in lib folder.
