+  <name>GNU Emacs</name>
+  <summary>Edit text files, view pictures and binary files</summary>
+  <description>
+    <p>
+      Emacs is a powerful, customizable, self-documenting, modeless
+      editor. It is used primarely to edit text, including text
+      documents, source code of programs, web pages and XML documents,
+      but can also be used to display and edit binary files.
+    </p>
+    <p>
+      Emacs allows efficient editing of text with shortcuts which
+      allow operating on letters, words, sentences, and paragraphs as
+      single units. This includes both moving around and operations
+      like copying, deleting, transposing, and pasting. Macros can be
+      conveniently defined to repeat sequences of commands. In
+      addition, Emacs is (partially) built in a scripting language
+      (elisp) which can also be used to define further functions
+      extending existing capabilities.
+    </p>
+    <p>
+      Emacs has extensive support for editing source code, including
+      programmable syntax highlighting, automatic indentation, source
+      code indexing, overview modes, and navigation based on language
+      specific units like functions and blocks. It is also possible to
+      invoke the compiler from within Emacs and easily move between
+      compiler output and corresponding positions in the source.
+    </p>
+    <p>
+      Emacs has multiple modules which provide further functionality.
+      This provides the capability to read mail, news, browse
+      pictures, read man and info pages, browse the web, execute
+      arbitrary programs, and more, without leaving the editor.
+    </p>
