# Makefile for the BOINC cube program
#
# Unpack this in boinc/apps/cube.d and say 'make cube' to make
# a BOINC application which demonstrates BOINC graphics.
#
# Can be built either using A) the directory in which BOINC was BUILT,
# or B) the location where BOINC was installed. Uncomment accordingly.
#
# Comments marked #MAC# show what needs to be changed for MacOS,
# but see the file Makefile.Mac for a working example.
