+   
+   CacheFile - Simple wrapper class for opening, generating and whatnot
+   
+   This class implements a simple 2 line mechanism to open various sorts
+   of caches. It can operate as root, as not root, show progress and so on,
+   it transparently handles everything necessary.
+   
+   This means it can rebuild caches from the source list and instantiates
+   and prepares the standard policy mechanism.
