DCIGDR

DCIGDR decodes IGDR data in BUFR format from a real-time 
data feed, or from a file fed to the program through standard 
input, and writes the data to an ASCII 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:
    
	dcigdr [options] output_file

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

	dcigdr -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.

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


The format of the output ASCII file is as follows:

YYYY MM DD HH MM Lat Lon Observation

where:

YYYY			Year

MM			Month of Year

DD			Day of Month

HH			Hour of Day

MM			Minute of Hour

Lat			Latitude of Observation

Lon			Longitude of Observation

Observation		Significant Wave Height in meters
