SUMMARY="Command-line driven graphing utility"
DESCRIPTION="Originally created to allow both students and scientists to \
visualize mathematical functions and data interactively, but has grown to \
support many non-interactive uses such as web scripting. It is also used \
as a plotting engine by third-party applications like Octave."
