4.5 Are we there, yet?

Yes, we are!

From now on, whenever you begin a new project, you can copy the last revision of the Makefile, then make fhe following changes:

• change the defintion of CSRC to reflect all the C source files, remember to use a space (not a comma) to separate name!
• change the definition of CCSRC to reflect all the C++ source files
• change main to whatever you want to name the final executable
• optionally change CXXFLAGS for compiler options (more warnings, more optimization, etc.)
