Not in 'gb.util', which cannot depend on any external library, and 
should not depend on external tools. 'gb.util' is only for adding less 
common small functions and features to the language.

A common interface to the underlying various archive tools should have 
its own component.

Installing package is something entirely system et distribution 
specific, so it should have its own component too.

Moreover, this feature seems to have already been standardized with 
'PackageKit', so maybe one should look at it first.
