#        Usage: make              (generate executable                      )
#               make clean        (remove objects, executable, prerequisits )
#               make tarball      (generate compressed archive              )
#               make zip          (generate compressed archive              )

#        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.
