    (description
     "The GNU plotutils package contains software for both programmers and
technical users.  Its centerpiece is libplot, a powerful C/C++ function
library for exporting 2-D vector graphics in many file formats, both vector
and raster.  It can also do vector graphics animations.

libplot is device-independent in the sense that its API (application
programming interface) does not depend on the type of graphics file to be
exported.

Besides libplot, the package contains command-line programs for plotting
scientific data.  Many of them use libplot to export graphics.")
