students editing output

[Edward Tecot]

Since the original request came from CMU, I thought I'd get the discussion
back on track.  The scope of the problem is where we have 600 students in an
introductory programming course who are required to hand in a few
programming assignments.  Demos are unreasonable due to the size of the
course.  The students already hand in the assignments electronically.  They
are also required to demo their programs inside of a script-like shell.
These students are not advanced enough to be able to impose user-interface
guidelines.  The problem stems from actually determining whether or not the
file is an actual script, and not a fake.  The solution that (to my
knowledge, which is not much, since I am no longer associated with the
course) is being attempted is to have the script program time-stamp the
file, like rogue saves; and have the handin program check this stamp.  There
seems to be no other way to reasonably approach this.  Suggestions in this
new light are welcomed.
