- * parse_args
- *
- * PURPOSE:  Sets encoding parameters to the specifications of the
- * command line.  Default settings are used for parameters
- * not specified in the command line.
- *
- * SEMANTICS:  The command line is parsed according to the following
- * syntax:
- *
- * -j  turns on JACK input
- * -V  turns on libVLC input
- * -L  turns on audio level display
- * -m  is followed by the mode
- * -y  is followed by the psychoacoustic model number
- * -s  is followed by the sampling rate
- * -b  is followed by the total bitrate, irrespective of the mode
- * -d  is followed by the emphasis flag
- * -c  is followed by the copyright/no_copyright flag
- * -o  is followed by the original/not_original flag
- * -e  is followed by the error_protection on/off flag
- * -f  turns off psy model (fast mode)
- * -q <i>  only calculate psy model every ith frame
- * -a  downmix from stereo to mono 
- * -r  turn off padding bits in frames.
- * -x  force byte swapping of input
- * -g  swap the channels on an input file
- * -t  talkativity. how verbose should the program be. 0 = no messages. 
- *
- * If the input file is in AIFF format, the sampling frequency is read
- * from the AIFF header.
- *
- * The input and output filenames are read into #inpath# and #outpath#.
