gen_cmm_data.py:

 GENERAL DESCRIPTION
    This script is deprecated in favor if gen_cmm_data1.py and gen_cmm_data2.py.
    It is maintained here for backwards compatibility with older versions of the
    Trace32 scripts.
    
Usage:
   gen_cmm_data <targ_root> <temp_cmm_script_file_name>
   Examples:
      gen_cmm_data ..\\..\\.. temp_fname.cmm

Description:
   gen_cmm_data.py can be called from a CMM script to generate a temporary CMM
   script to initialize path information to the component builds.
