    """PGPLOT Graphics Subroutine Library.

    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."""
