+    <p>
+      NEdit-ng is a Qt port of the Nirvana Editor (NEdit) version 5.6. It is
+      intended to be a drop-in replacement for nedit, preserving the original
+      look, feel, and macro language while modernizing the codebase on top of
+      Qt.
+    </p>
+    <p>Features include:</p>
+    <ul>
+      <li>Syntax highlighting for many languages</li>
+      <li>Tabbed multi-document editing</li>
+      <li>Regular expression search and replace</li>
+      <li>Macro language for extending and automating the editor</li>
+      <li>Rectangular block selection and editing</li>
+      <li>Shell command integration and configurable user menus</li>
+      <li>Ctags-based tag lookup</li>
