grsync: grsync (rsync GUI)
grsync: 
grsync: Grsync is a GUI (Graphical User Interface) for rsync, the commandline
grsync: directory synchronization tool. 
grsync: It makes use of  the  GTK  libraries  and  is  released under the GPL
grsync: license, so it is opensource. It is in beta stage and doesn't support
grsync: all of rsync features, but can  be effectively  used  to  synchronize
grsync: local directories.
