A simple function for parsing os.Args

// parseArgs(os.Args)
func parsArgs(args []string) ([]string, map[string][]string) {
	argMap := make(map[string][]string)
	arguments := []string{}

	for i := 1; i < len(args); {
		if args[i][0] == '-' {
			j := i + 1
			argMap[args[i][1:]] = []string{}
			for j = i + 1; j < len(args) && len(args[j]) > 0 && args[j][0] != '-'; j++ {
				argMap[args[i][1:]] = append(argMap[args[i][1:]], args[j])
			}
			i = j
		} else {
			arguments = append(arguments, args[i])
			i++
		}
	}
	return arguments, argMap
}
