/bin/echo " - carousel_directory: the directory to marshal in an object carousel"
/bin/echo " - association_tag aka common tag, referenced by PMTs and AITs, every carousel has one"
/bin/echo " - modules_version, all the modules will have the same version, you need to change this to notify to the box files are changed, goes from 0 to 15"
/bin/echo " - pid, referenced by PMTs using this carousel"
/bin/echo " - carousel_id, referenced by PMTs using this carousel, every carousel has its own, it is an alternative for association_tag, they have the same function"
/bin/echo " - compress_mode, 0: don't compress, 1:compress all, 2:smart compress, file with .solo extension are set in an uncompressed module alone to allow use cases like quick image file update, default is 2"
/bin/echo " - padding_on, every section is padded, was useful with some buggy decoder, waste bandwidth, default off, unsupported since OpenCaster 2.4.8"
/bin/echo " - clean_off, don't delete temp file, default off, used for debug"
/bin/echo " - DDB_size, Use custom size for DDB payload, default = max = 4066"
/bin/echo " - sets the Update flag in the TransactionID of DSI and DII to the value given (0 or 1)"
/bin/echo " - mount_frequency, set how often insert DII/DSI/SGW to speed up carousel mount, default is twice per carousel period"
