Sherrie,

The cdl files are in the decoders directory  and they are with the
release also. The cdls change more often then the code so they are
seperate and the the seperate cdl's are more current.  I'm attaching the
LDM pqact entries for the decoders, shows the arguments for the decoders.
One can run the decoders from the command line redirecting the raw data to
STDIN.  The decoders are usually run as user LDM.
