 scripts, this overcomes the ``ssh`` limitation of not being able to
 specify the password on the command line.
 
+You can also use ``tsshbatch`` to ``GET`` and ``PUT`` files
+from- and to many hosts at once.

 ``tsshbatch`` also understands basic ``sudo`` syntax and can be used
 to access a host, ``sudo`` a command, and then exit.

+The last option on the command line is either an explicit command
+string or the ``-``.  If you provide an explicit command,
+``tsshbatch`` will attempt to execute it on every host you've
+specified either via ``-H`` or a ``hostlistfile``::
+
+  tsshbatch.py -Hmyhost ls -al /etc
+
+This will do a ``ls -al /etc`` on ``myhost``.
+
+Be careful when using metacharacters like ``&&, <<, >>, <, >`` and so
+on in your commands.  You have to escape and quote them properly or
+your local shell will interfere with them being properly conveyed to
+the remote machine.
+
+If ``tsshbatch`` sees a ``-`` character, it will read commands to
+execute from stdin.  This is the preferred way of doing multiple
+commands in a single run of ``tsshbatch``::
+
+  tsshbatch.py ..... <mycommands
+
+This will read the file ``mycommands`` and attempt to execute
+every line in that file as a command on the remote hosts.
+Specifying ``-`` without such redirection means you want to
+enter commands manually from the keyboard.
+
+``tsshbatch`` does all the ``GETs``, then all the ``PUTs`` before
+attempting to do any command processing.  If no ``GETs``, ``PUTs``, or
+commands have been specified, ``tsshbatch`` will exit silently, since
+"nothing to do" really isn't an error.
