+ <description>
+   <p>
+     PyMOL is one of a few open-source visualization tools available
+     for use in structural biology. The Py portion of the software's
+     name refers to the fact that it extends, and is extensible by the
+     Python programming language.
+   </p>
+   <p>
+     PyMOL has the ability to load, manipulate and visualize molecules
+     from a variety of formats and sources.  The program can easily be
+     controlled using a menu-driven GUI, or from a large number of
+     commands and/or scripts.  A built-in raytracer is available to
+     generate high-quality images of the views generated in the GL
+     portion of the GUI.
+   </p>
+   <p>
+     PyMOL uses OpenGL Extension Wrangler Library (GLEW) and Freeglut,
+     and can solve Poisson–Boltzmann equations using the Adaptive
+     Poisson Boltzmann Solver (apbs).
+  </p>
+  <p>
+    Install this application to view, analyze, and prepare graphics
+    images of proteins and experimental strucural data
+    (e.g. crystallographic, NMR and electron microscopy based).
+  </p>
