Checking dependency

["Rajkumar S." <voidmain@xxxxxxxxxxxxx>]

Hi,

I have a small script (attached) that I use to copy files from a
repository of all rpms to the directory from where I burn the CD.
basically what I intend to do is to make a single RedHat CD with all the
updates for a server class installation. For that I have trimmed the comps
file to remove the X and other unwanted stuff. My script (hopefully)
copies all the packages that are listed in the comps file to the destdir,
from where I burn the CD.

Now I want to add dependency check to this script, so that after copying
it will run the dependency check and will inform if their are any
problems.

The anaconda has a function to find out dependency problems, but I could
not figure out which. Any help here will be much appreciated.
