Several packaging systems has 3 levels of relations.
stuff that must be there. 
     RPM-language: Requires. Deb-language: Depends.

optional stuff that should be there by default on normal systems
     RPM-language: Recommends. Deb-language: Recommends

Optional stuff that gives something extra
     RPM-language: Suggests. Deb-language: Suggests.

Maybe we could be inspired by that?

Note that on debian systems, apt and aptitude installs Depends and Recommends 
by default, and allows Recommends to be removed without removing other 
package.
Yum don't know about Recommends nor Suggests and just installs Required 
packages.

Genius, I cannot doubleclick the OpenGL fan over a file to the ISA attachment 
on the device of the fan, how does it work?
