The CCSM4 scripts have been significantly upgraded from CCSM3 and are
based on a completely different design philosophy. The new scripts will
generate a set of "resolved scripts" for a specific configuration determined
by the user. The configuration includes components, resolution, run type, and
machine. The run and setup scripts that were previously in the /scripts
directory for CCSM3 are now generated automatically. See the CCSM4 User's
Guide for information on how to use the new scripts:

The file that contains the ice model namelist is now located in $CASE/Buildconf. The script containing the environment variables used for building the executable file for the ice model is also in $CASE/Buildconf. The contents of the ice model namelist are described in section 3.
