一个GNU Makefile的示例
#===============================================================================
#
# Filename: Makefile
# Description:
#
# Usage: make (generate executable )
# make clean (remove objects, executable, prerequisits )
# make tarball (generate compressed archive )
# make zip (generate compressed archive )
#
# Version: 1.0

# Notes: This is a GNU make (gmake) makefile.
# C extension : c
# C++ extensions : cc cpp C
# C and C++ sources can be mixed.
# Prerequisites are generated automatically; makedepend is not
# needed (see documentation for GNU make Version 3.81, April 2006,
# section 4.13). The utility sed is used.
