+ Cache - Structure definitions for the cache file
+
+ Please see doc/apt-pkg/cache.sgml for a more detailed description of
+ this format. Also be sure to keep that file up-to-date!!
+
+ Clients should always use the CacheIterators classes for access to the
+ cache. They provide a simple STL-like method for traversing the links
+ of the datastructure.
+
+ See pkgcachegen.h for information about generating cache structures.
