+  <description>
+    <p>
+      GNU Octave is a high-level interpreted language, primarily intended for
+      numerical computations. It provides capabilities for the numerical
+      solution of linear and nonlinear problems, and for performing other
+      numerical experiments. It also provides extensive graphics capabilities
+      for data visualization and manipulation. Octave is normally used through
+      its interactive command line interface, but it can also be used to write
+      non-interactive programs. The Octave language is quite similar to
+      Matlab so that most programs are easily portable.
+    </p>
+    <p>
+      Octave has extensive tools for solving common numerical linear algebra
+      problems, finding the roots of nonlinear equations, integrating ordinary
+      functions, manipulating polynomials, and integrating ordinary
+      differential and differential-algebraic equations. It is easily
+      extensible and customizable via user-defined functions written in
+      Octave's own language, or using dynamically loaded modules written in
+      C++, C, Fortran, or other languages.
