-   Version - Version comparison routines
+   Version - Versioning system..
+
+   The versioning system represents how versions are compared, represented
+   and how dependencies are evaluated. As a general rule versioning
+   systems are not compatible unless specifically allowed by the 
+   TestCompatibility query.

    
    

-   These routines provide some means to compare versions and check
-   dependencies.
+   The versions are stored in a global list of versions, but that is just
+   so that they can be queried when someone does 'apt-get -v'. 
+   pkgSystem provides the proper means to access the VS for the active
+   system.
