tomwalters@296:  * \brief AIM-C replacement for HTK's HCopy
tomwalters@296:  *
tomwalters@296:  * The following subset of the command-line flags
tomwalters@296:  * should be implemented from HCopy:
tomwalters@296:  *  -A      Print command line arguments         off
tomwalters@296:  *  -C cf   Set config file to cf                default 
tomwalters@296:  * (should be able to take multiple config files)
tomwalters@296:  *  -S f    Set script file to f                 none
tomwalters@296:  *  //! \todo -T N    Set trace flags to N                 0
tomwalters@296:  *  -V      Print version information            off
tomwalters@296:  *  -D of   Write configuration data to of       none
