description                 A command-driven interactive function plotting program

long_description            Gnuplot is a command-driven interactive function \
                            plotting program. Plots any number of functions, \
                            built up of C operators, C library functions, and \
                            some things C does not have like **, sgn(), etc. \
                            Also support for plotting data files, to compare \
                            actual data to theoretical curves.
