CacheFile - Simple wrapper class for opening, generating and whatnot
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.
