infile            use the given dbconfig-common config file as input
	-f|--format       use the given output format (must be specified)
	-a|--all          include all information in output (default)
	-b|--basepath     include the basepath in the output

	-t|--dbtype       include the dbtype in the output
	-h|--help         display this helpful message

format is one of a list of include-file style formats for various
	programming languages.  the current list includes:
		sh - /bin/sh style include file
		perl - perl parseable include file
		php - php parseable include file
		exec - run the file as a script and interpret its output.
