+UDR is a wrapper around rsync that enables rsync to use UDT protocol and
+thus improves throughput of large data transfers over long distances.
+
+UDT is a UDP-based, application level protocol. It is designed to
+support transferring large datasets over high speed wide area networks,
+where TCP has been known to be extremely ineffective.
+
+UDR does not change rsync, it works by creating a UDT connection and
+then places the connection between the rsync client and server.
+
+To use UDR, prefix the current rsync command used to transfer data with
+'udr', for example:
+
+udr rsync -avz /home/user/dir/ user@example.com:/home/user/dir
+
+Any rsync options can be used.
+
+UDR must be on the client and server machines that data will be
+transferred between. UDR uses ssh to do authentication and automatically
+start the server-side UDR process. At least one UDP port needs to be
+open between the machines.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
