regtool help/version patch


Here is the --help, --version patch for regtool. I reorganized the
usage output in a hopefully more logical manner. As Corinna suggested
for some of the other utils, --help produces more verbose output, but
an error usage() still retains useful info. I also added a check for
(_argv[optind+1] == NULL) after the getopt, which was causing a core
dump on 'regtool get' with no KEY.

ChangeLog:

2002-06-02  Joshua Daniel Franklin <joshuadfranklin@yahoo.com>

	* regtool.cc (prog_name): New global variable.
	(longopts): Ditto.
	(opts): Ditto.
	(usage): Standardize usage output. Rearrange/add descriptions.
	(print_version): New function.
	(main): Accomodate longopts and new --help, --version options.
	Add check for (_argv[optind+1] == NULL).
