description         C/Fortran graphics library

long_description    The PGPLOT Graphics Subroutine Library is a Fortran- or \
                    C-callable, device-independent graphics package for making \
                    simple scientific graphs. It is intended for making \
                    graphical images of publication quality with minimum \
                    effort on the part of the user. For most applications, the \
                    program can be device-independent, and the output can be \
                    directed to the appropriate device at run time.
