Currently, command line argument parsing is not compatible with getopt/s. I'd like to support getopt-ish parsing as well as short flags. For example,

• --long-option=value => --long-option value
• -odir => -o dir
• -ab => (known that options -a and -b do not consume next arg) -a -b
• -abvalue => (known that option -a consumes next arg) -a bvalue
• -abvalue => (known that only option -b consumes next arg) -a -b value
