 * Brief synopsis: psxy will read <x,y> points and plot symbols, lines,
 * or polygons on maps.
 *
 * Note on KEYS: S?(=2 means if -S~|q then we may possibly take optional crossing line file, else the ? is set to ! for skipping it.
 *               The "2" means we must skip two characters (q|~ and f|x) before finding the dataset file name
