This is an mostly abstract class. You should subclass it and implement the
methods to get something useful.

The parameter 'stage' is one of "upgrade", "install"
(both sent before unpacking), "configure", "trigproc", "remove",
"purge". This method is used for dpkg only.

This functions runs install actions. The parameter 'obj' may either
be a PackageManager object in which case its do_install() method is
called or the path to a deb file.
If the object is a PackageManager, the functions returns the result
of calling its do_install() method. Otherwise, the function returns
the exit status of dpkg. In both cases, 0 means that there were no
problems.
