-# Version 4.1 - 2016-10-07, Marcus M. Darden (mmdarden@umich.edu)
-#   * Allow test rules to worry without a defined PROJECTFILE
-#   * COPYFILE_DISABLE=true sets an environment variable that prevents MacOS
-#     from doing messy things while making tarballs
-#   * make clean now removes .dSYM directories from MacOS compilation
-#   * make debug now builds EXECUTABLE_debug
-#       1. make clean
-#       2. make -rR
-#       3. make debug
-#     Will generate both an executable and executable_debug properly
-#   * Added -Wconversion to prevent conversion oversights
-# Version 4 - 2015-05-03, Marcus M. Darden (mmdarden@umich.edu)
-#   * Updated build rules for tests
-# Version 3.0.1 - 2015-01-22, Waleed Khan (wkhan@umich.edu)
-#   * Added '$(EXECUTABLE): $(OBJECTS)' target. Now you can compile with
-#     'make executable', and re-linking isn't done unnecessarily.
-# Version 3 - 2015-01-16, Marcus M. Darden (mmdarden@umich.edu)
-#   * Add help rule and message
-#   * All customization locations are cleary marked.
-# Version 2 - 2014-11-02, Marcus M. Darden (mmdarden@umich.edu)
-#   * Move customization section to the bottom of the file
-#   * Add support for submit without test cases, to prevent submission
-#     deduction while testing, when code fails to compile
-#       usage: make partialsubmit  <- includes no test case files
-#              make fullsubmit     <- includes all test case files
-#   * Add automatic creation of test targets for test driver files
-#       usage: (add cpp files to the project folder with a test prefix)
-#              make alltests       <- builds all test*.cpp
-#              make test_insert    <- builds testinsert from test_insert.cpp
-#              make test2          <- builds testinsert from test2.cpp
-#   * Add documentation and changelog
-# Version 1 - 2014-09-21, David Snider (sniderdj@umich.edu)
