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 meant as a debug aide.
+ It uses the command line interface common to all the APT tools.
Returns 100 on failure, 0 on success.
