# This is a Makefile for the GUI that is used in Chapters 12-17 of
# "Programming -- Principles and Practice Using C++" by Bjarne Stroustrup
#

#
# Usage:
#     make           - Build the library.
#     make clean     - Delete object files and the library.
#     make veryclean - Delete object files and the library.
#                      Also gets rid of emacs backup files, core files,
#                      and other such cruft.
