+    <_p>Ristretto is an image viewer for the Xfce desktop environment.
+    </_p>
+    <_p>The Ristretto Image Viewer is an application that can be used to view
+       and scroll through images, run a slideshow of images, open images with
+       other applications like an image-editor or configure an image as the 
+       desktop wallpaper.

+      <description>
+        <_p>This version comes with the improvements such as thumbnail usage as appicon
+           and update to the first image in the image-list when receiving a ready-signal,
+           required to show the thumbnail once it's generated.

+      <description>
+        <_p>This release contains lots of translation-updates,
+           and a crash when configuring the 'limit-quality' property.

+
+    <release version="0.6.0" timestamp="1335662454">
+      <description>
+        <_p>This version comes with several changes such as online documentation on
+           http://docs.xfce.org, the option to limit the maximum image-quality to
+           the screen dimensions to improve memory-usage and performance - now ristretto
+           renders at full quality with this option disabled, only one toolbar - instead 
+           of two, a quick-launch button on the toolbar to execute an editor, the option
+           to pick a default-editor per mime-type, an optional clock that shows up when
+           ristretto is fullscreen, Ristretto now shows a 'Loading..' message in the 
+           statusbar to indicate when it is busy and progressive loading of directories to
+           prevent lockup of the UI.
+           This version is designed to work with version 4.10 of Xfce.
