+ apt-cache - Manages the cache file.
+
+ This program should eventually handle both low and high level
+ manipulation of the cache file. Depending how far things go it
+ might get quite a sophisticated UI.
+
+ Currently the command line is as follows:
+ apt-cache add cache file1:dist:ver file2:dist:ver ...
+ ie:
+ apt-cache add ./cache Pacakges:hamm:1.0
+
+ A usefull feature is 'upgradable' ie
+ apt-cache upgradable ./cache
+ will list .debs that should be installed to make all packages the latest
+ version.
+
+ Returns 100 on failure, 0 on success.
