so the idea is this - if I want a list of all the groups I use grouplist
w/no options or with installed, available.

if I want a list of pkgs in a group I use grouplist "specific groupname
or wildcard"

ok, that's fine - works for me.

I'd like to address the use of pkgTree though. I thought giving some
more useful output would be handy.

So maybe for any given group it lists the groupreqs as subgroups and
then it lists the pkgs and their types.


ie:
Group Foo
 SubGroups:
 subgrp1
 subgrp2
 subgrp3

Default Metapkgs:
 emacs

Optional Metapkgs:
 does
 anyone
 care?

Mandatory Pkgs:
 foo
 bar
 baz
 quux

Default Pkgs:
 no
 way
 really?

Optional Pkgs:
 do
 we
 care?


So people get a more complete view of pkgs that would get installed.
Much of this code is already written in the semi-private
yumcomps.Groups_Info._dumppkgs

Look at what it does then consider writing a mini function of
pkgaction.py to do display of group information.

The display format is yours to do with what you will.

oh and _dumppkgs is just there and useful if you want to use yumcomps.py
independent of yum. It should run standalone quite nicely.
