+
+ 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.
+
+ 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.
