+    (description "KmPlot is a powerful mathematical plotter, capable of
+plotting multiple functions simultaneously and combining them into new
+functions.
+
+Cartesian, parametric, and differential functions are supported, as well as
+functions using polar coordinates.  Plots are printed with high precision at
+the correct aspect ratio.  The graphs can be colorized and the view is
+configurable, is scalable, and can be zoomed.
+
+KmPlot also provides numerical and visual features such as filling and
+calculating the area between the plot and the first axis, finding maxima and
+minima, changing function parameters dynamically, and plotting derivatives
+and integral functions.
+
+This package is part of the KDE education module.")
