+ <summary>The LibreOffice productivity suite</summary>
+ <description>
+  <p>LibreOffice is a powerful office suite.  Its clean interface and
+  feature-rich tools help you unleash your creativity and enhance your
+  productivity.  LibreOffice includes several applications that make it the most
+  powerful Free and Open Source office suite on the market: Writer (word
+  processing), Calc (spreadsheets), Impress (presentations), Draw (vector
+  graphics and flowcharts), Base (databases), and Math (formula editing).</p>
+  <p>LibreOffice supports opening and saving into a wide variety of formats, so
+  you can easily share documents with users of other popular office suites
+  without worrying about compatibility.</p>
