 I will consider for bonus points the implementation of a "check" argument, which if provided on your script's command-line, will perform necessary tallys and sanity checks (for example, if a project is out of 39 points, do all your values check out; similarly, do all the line-by-line point items add up to the reported total you have?), and nicely displays any inconsistencies (so that you can report them to me for potential correction). I will consider for bonus points the implementation of a "check" argument, which if provided on your script's command-line, will perform necessary tallys and sanity checks (for example, if a project is out of 39 points, do all your values check out; similarly, do all the line-by-line point items add up to the reported total you have?), and nicely displays any inconsistencies (so that you can report them to me for potential correction).

 +====bash debugging====
 +If you add a **-x** argument to bash (in the shabang, or on the command-line if running your script that way), it will be immensely more verbose, reporting more precisely on its actions. This can prove most useful when trying to figure out various problems, be it syntax errors in your script or spurious logic errors.
