# Makefile for gnuplot LaTeX tutorial

# default target
all: tutorial.dvi

# this tells GNU make not to export variables into the environment
# But other makes dont understand its significance, so it must
# not be the first target in the file. So it is here, before
# any variables are created, but after the default target
