Pungi should also be looked into.  Depends on where in the "tree" building 
process you want to be.

Pungi builds the "rpm" tree part of a RHEL release.  It takes as input 
kickstart files which specify where to get rpms from and which rpms to 
place in the tree.  This is known as the "gather" step of Pungi.

Pungi also can call "lorax" to build the files that 
reside in /images/  which include boot.iso and the pxe files.

Pungi can take the full build tree and create the 'DVD' install media.

So it depends on what you have to start with and what you want as the 
result.
