+       "@code{MODULARIZE} is an attempt at providing a common interface to
+segregate major application components.  This is achieved by adding special
+treatment to packages.  Each module is a package that is specially registered,
+which allows it to interact and co-exist with other modules in better ways.  For
+instance, by adding module definition options you can introduce mechanisms to
+tie modules together in functionality, hook into each other and so on.")
