define Package/gnuplot-ggi/Default/description
  Gnuplot  is a portable command-line driven graphing utility for linux, OS/2, 
  MS Windows, OSX, VMS, and many other platforms.  This version is compiled
  to use LibGGI as default terminal, allowing gnuplot to draw directly to
  the Linux framebuffer.
