Updating Lab Project files...could be wrong, but I think that Labs 0 through 4 are not up to date.  I need to pull them from the UNIX Sandbox Git Server at school to make sure the versions in here are up-to-date.

Labs 5, 6, and 7 are DEFINITELY up to date (Lab 5 is done, except for the Makefile and Readme, which still need to be made).
