 * Simple but powerful command line parsing.

 * #include <stdlib.h>
 * 
 * static bool someflag;
 * static int verbose;
 * static char *somestring;

 *			"Set someflag"),
 * 	OPT_WITH_ARG("--somefile=<filename>", opt_set_charp, opt_show_charp,
 *		     &somestring, "Set somefile to <filename>"),
 * 	OPT_WITHOUT_ARG("--usage|--help|-h", opt_usage_and_exit,
 * 			"args...\nA silly test program.",
 *			"Print this message."),
 * 	OPT_ENDTABLE
 * };
 * 
 * int main(int argc, char *argv[])

 * 	int i;
 *
