yum grouplist does not show all groups

[Özgür]

Hi,

The command

yum grouplist

does not show all available groups in Fedora 19. I had the same problem 
before in CentOS and other versions of Fedora. As an example, I can 
install

yum groupinstall "Development Libraries"

but yum grouplist does not show such a group. Is that a bug, or am I doing 
something wrong?
