The groups in comps.xml is used as meta-packages, there can be installed 
and removed. just like yum groupinstall/groupremove.
Ex. you can install KDE by installing the kde-desktop meta-package.
All the meta-packages (comps groups) are located under collections.
The categories is not used in pk-application.
