+     "wxMaxima is a graphical user interface for the Maxima computer algebra
+system.  It eases the use of Maxima by making most of its commands available
+through a menu system and by providing input dialogs for commands that require
+more than one argument.  It also implements its own display engine that
+outputs mathematical symbols directly instead of depicting them with ASCII
+characters.
+
+wxMaxima also features 2D and 3D inline plots, simple animations, mixing of
+text and mathematical calculations to create documents, exporting of input and
+output to TeX, and a browser for Maxima's manual including command index and
+full text searching.")
