#
# This is a common Makefile for code examples from the book
# "Programming -- Principles and Practice Using C++" by Bjarne Stroustrup
#

#
# Usage:
#     make           - Build all examples
#     make clean     - Clean all examples
#     make veryclean - Clean all examples.
#                      Also gets rid of emacs backup files, core files,
#                      and other such cruft.
#     make test      - Run the test suite
