+ * @brief Comanche Page Description Language.
+ *
+ * Comanche is a markup language similar to bbcode with which to create elaborate
+ * and complex web pages by assembling them from a series of components - some of
+ * which are pre-built and others which can be defined on the fly. Comanche uses
+ * a Page Decription Language to create these pages.
+ *
+ * Comanche primarily chooses what content will appear in various regions of the
+ * page. The various regions have names and these names can change depending on
+ * what layout template you choose.
