Do we need these, INFO_INSTALL and INFO_AVAILABLE if fine.

we are using GROUP_META_PACKAGES to get the meta packages.

./yumBackend.py search-group none 'meta-packages'

will show all the meta packages.

.yumBackend.py install-packages 'kde-desktop;meta;meta;meta'

will install the metapackage 'kde-desktop'

.yumBackend.py remove-packages no 'games;meta;meta;meta'

will remove the metapackages 'games'

.yumBackend.py get-requires none 'games;meta;meta;meta' no

will return the requirement of the packages and deps of the 'games' 
metapackage.

this work in the current yum backend in git, what else do we need ?
