# show how to use this
usage = flagopt.draw(flags)

content = (
  # move right linearly
  '-move -x 10 '
  # then move diagonally right and down;
  # no need to explicitly pass the first flag (-x)
  '-move 5 -y -5 '
  # backslash is used as an escape character;
  # -target will be ignored during the first parse scan
  # and the backslash will be removed so that -target can
  # be considered during the next scan for -scavenge;
  # multiple backslashes can be used to achieve other
  # amounts of iterations for this effect
  '-scavenge \-target wood '
  # arguments can be passed multiple times (-time);
  # scavenge for 3 hours and 60 more wood after that
  '-finish -time 3 -limit 60 '
  # or until 5 hours have passed
  '-finish -time 5'
  # rest for 4 hours, craft a tent, rest for another 3;
  # there is no space between 5 and -rest (line above);
  # spaces do not matter for flags and are stripped away
  # unless there is an escape character before / after
  '-rest 4      '
  # you can pass empty flags,
  # their presence is indicated with an empty string
  '--debug '
  # im bad at coming up with examples
  '-craft spear '
  # especially when they involve games
  '-target rabbit '
  # time to sleep now
  '-rest 3'
