# Author: Seth A. Yoder 6/15/2013, the day I got tired of manually renaming things.
# Description: Refactoring tool for c++ projects. Stick this script in the top level of your project directory. I'm
#              currently assuming your makefile is there, and assuming it has "akefile" in its name, and that there is
#              only one file named as such.

# I haven't checked against every edge case. Back up your files before you use this. However, if anything goes wrong,
# nothing should happen besides compiler errors.

#make clean
