DCACFT

    DCACFT decodes raw AIREP, PIREP, RECCO and AMDAR reports from a
    real-time data feed, or from a file fed to the program through 
    standard input, and writes the data to a GEMPAK surface file.  The 
    program is controlled by inputs to the command line.

    The inputs are program options and the output file name or template.
    For example, for real-time data feeds:
    
	dcacft [options] output_file

    Currently, for real-time operation, each output file represents
    a single hour, of the form YYMMDDHH.acf.

    If running the program interactively with standard input, the -c
    option must be used.  The input file must be also be specified.
    For example:

	dcacft -c YYMMDD/HHNN [other_options] output_file < input_file
    
    A template may be used to specify the output file name.  The file
    name template uses the date and time of the bulletin or report
    to replace the following characters.

	YY		Year without the century
	MM		Month number
	DD		Day
	HH		Hour
	NN		Minute
