You can only insert files into this directory, you can not remove them or overwrite them. So please make sure that you really want to turn in your file. If you must turn in a second version of your file, please e-mail me letting me know (lbowser@andrew.cmu.edu) and rename it to something like hw1version2.txt or some other name that I can tell which version you want me to look at. If you turn in the second version late, I will not look at it, and only look at the latest version turned in before the deadline unless other (prior) arrangements have been made with Professor Orgass.
