# alt_getopt is a command options parser, it gets options
# specification and application's options as arguments and outputs
# shell commands to be executed.
# Usage:
# alt_getopt -h
# alt_getopt [OPTIONS] opt1 sh_cmd1 [opt2 sh_cmd2...] -- [args]
# OPTIONS:
# -h|--help display this screen
# -c do not output 'shift' command, variable
# __shifts_cnt is assigned instead
