[CentOS-devel] anaconda dependency calculation?

Hi all,

I'm trying to find a tool that calculates all dependencies for a 
specific package or group of packages for use with CentOS 5 (beta) with 
the intention of putting together a custom single CD build of CentOS 5. 
With CentOS 4 i used a python script that used the hdrlist module to 
find all dependencies which borrowed code from a number of sources.

I've looked at yumdownloader and how it checks dependencies (using the 
--resolve option) but if i pass it the list of packages defined in say 
the Base and the Core yum groups which generally form an absolute 
minimal install i end up with about 200 packages. If i do a custom 
install (using beta 1 disks) and deselect everything i end up with over 
300 packages.

So i'm guessing anaconda calculates dependencies in a slightly different 
way, can anyone point me to files/code where i should be looking to find 
out?

Thanks very much in advance for help
Nick
