apt-cache - Manages the cache files
apt-cache provides some functions fo manipulating the cache files.
It uses the command line interface common to all the APT tools. The
only really usefull function right now is dumpavail which is used
- by the dselect method. Everything else is ment as a debug aide.
+ by the dselect method. Everything else is meant as a debug aide.
Returns 100 on failure, 0 on success.
