+      gThumb is an image viewer, editor, browser and organizer.  It is designed
+      to be well integrated with the GNOME 3 desktop.
+    </_p>
+    <_p>
+      As an image viewer gThumb allows to view common image file formats
+      such as BMP, JPEG, GIF (including the animations), PNG, TIFF, TGA and
+      RAW images.
+      It is also possible to view various metadata types embedded inside an
+      image such as EXIF, IPTC and XMP.
+    </_p>
+    <_p>
+      As an image editor gThumb allows to scale, rotate and crop the images;
+      change the saturation, lightness, contrast as well as other color
+      trasformations.
+    </_p>
+    <_p>
+      As an image browser gThumb shows the thumbnails of the images saved on
+      your disk, allows to perform the common operations of a file manager such
+      as copy, move and delete files and folders.
+      Furthermore there is a series of image specific tools such as JPEG
+      lossless transformations; image resize; format conversion; slideshow;
+      setting an image as desktop background and several others.
+    </_p>
+    <_p>
+      As an image organizer gThumb allows to add comments and other metadata to
+      images; organize images in catalogs and catalogs in libraries; search
+      for images and save the result as a catalog.
