Usage: toast [-fcpdhvaulsFC] [files...]

 -f  force     Replace existing files without asking
 -c  cat       Write to stdout, do not remove source files
 -d  decode    Decode data (default is encode)
 -p  precious  Do not delete the source

 -u  u-law     Force 8 kHz/8 bit u-law in/output format
 -s  sun .au   Force Sun .au u-law in/output format
 -a  A-law     Force 8 kHz/8 bit A-law in/output format
 -l  linear    Force 16 bit linear in/output format

 -F  fast      Sacrifice conformance to performance
 -C  cutoff    Ignore most samples during LTP
 -v  version   Show version information
 -h  help      Print this text
