+  <description>
+    <_p>Grsync is a GUI (Graphical User Interface) for rsync, the commandline directory
+and file synchronization tool. It can be effectively used to synchronize local
+directories and it supports remote targets as well (even though it doesn't
+support browsing the remote folder). Sample uses of grsync include: synchronize
+a music collection with removable devices, backup personal files to a networked
+drive, replication of a partition to another one, mirroring of files, etc.</_p>
