+dit(bf(--log-file=FILE)) This option causes rsync to log what it is doing
+to a file. This is similar to the logging that a daemon does, but can be
+requested for the client side and/or the server side of a non-daemon
+transfer. If specified as a client option, transfer logging will in effect
+if the bf(--log-format) option was either specified or implied (e.g.
+bf(--verbose) implies a basic log format). If explicitly sent to a server
+via the bf(--rsync-path) option, transfer logging will always occur using
+the default bf(--itemize-changes) format.
+
+Here's a example command that requests the remote side to log what is
+happening:
+
+verb( rsync -av --rsync-path="path --log-file=/tmp/rlog" src/ dest/)
+
+This is very useful if you need to debug why a connection is closing
+unexpectedly.
