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.
