• (10/19) There's a correction below. When all boxes reach target squares, you print "Exiting program" with a period after "program", not an exclamation point. See below.
• Use the following BNF for BOX_INFO and BOX_INFO_SORTED

  <boxinfo-out> := "  The [" <box-color> "] box is at " <coord> <endl>
                    <boxinfo-show-food>
                      "  The [" <box-color> "] box " [ "IS" | "IS NOT" ]
                         " on a target square" <endl>
                      "  The [" <box-color> "] box weighs "
                          <udigits> " units" <endl>
  
  <boxinfo-show-food> := Food items" <endl>
                           "----*----*"  <endl>
                           [ <food-list> | <no-food-box> ]
                           <endl> <total-points>
        <no-food-box> := "  [" <box-color> "] box has no food items on it" <endl>
         <food-items> := [ <food> ]+
         <food>       := "(" <udigits> ") [" <name-of-item> "]" <udigits> " pts" <endl>
    <boxtotal-points> := "The box holds (" <udigits> ") total pts" <endl>
  

  You can also read this in the main P2 specs.

• (10/17) Even though the project description says there may be 0 boxes and 0 target squares, assume there is at least one box and one target square. This will simplify matters when it comes to ending the game (i.e., the game won't end automatically).
• (10/14) Be able to handle upper and lowercase for the XML-like tags (e.g., <box>, </box>, <BOX>, </BOX>, <Box>, etc. should all be valid). Hint: Make a copy of the string read in, convert to lowercase, and test the copy.
• (10/14) If all target squares are filled with boxes after a move, do the following:
  • Print a newline.
  • Print

    *** YOU WIN! ALL BOXES ON TARGET SQUARES!!! *** <endl>
    

  • Print the output used by DISPLAY (without the command echo for DISPLAY). The command echo won't appear, since this is an atypical situation, not caused by a command.
  • Then print the "Exiting program! Thanks for playing!" (and newline), at the end, and do not process any more commands. CORRECTION: Print "Exiting program. Thanks for playing!" There should be an exclamation mark only after the second line.

• (10/13) You must complete the entire move, before determining whether all boxes are on target squares. Suppose there is one box and one target square. The player moves the box, and it passes over the target square, but does not end up on the target square once that single move is complete (e.g. moving east 4 units). In that case, the game continues on. Only when all boxes are on target squares at the END of a single command, do you quit the game.
• (10/13) No command echo is made when </command> is encountered. However, the output message for QUIT still occurs.
• (10/13) Player CAN be placed on top of a target square, initially. If so, just print the "=" for the player (thus, there is no indication of the player being on a target square, other than there is one fewer target square visible).
• (10/13) Player will NOT be placed on top of a food item, initially.
• (10/13) Player will NOT be placed on top of a square with a box, initially.
