+"""Automate Audacity via mod-script-pipe.
+
+Pipe Client may be used as a command-line script to send commands to
+Audacity via the mod-script-pipe interface, or loaded as a module.
+Requires Python 3.
+(Python 2.7 is now obsolete, so no longer supported)
+
+======================
+Command Line Interface
+======================
+
+    usage: pipeclient.py [-h] [-t] [-s ] [-d]
+
+Arguments
+---------
+    -h,--help: optional
+        show short help and exit
+    -t, --timeout: float, optional
+        timeout for reply in seconds (default: 10)
+    -s, --show-time: bool, optional
+        show command execution time (default: True)
+    -d, --docs: optional
+        show this documentation and exit
+
+Example
+-------
+    $ python3 pipeclient.py -t 20 -s False
+
+    Launches command line interface with 20 second time-out for
+    returned message, and don't show the execution time.
+
+    When prompted, enter the command to send (not quoted), or 'Q' to quit.
+
+    $ Enter command or 'Q' to quit: GetInfo: Type=Tracks Format=LISP
+
+============
+Module Usage
+============
+
+Note that on a critical error (such as broken pipe), the module just exits.
+If a more graceful shutdown is required, replace the sys.exit()'s with
+exceptions.
+
+Example
+-------
+
+    # Import the module:
+    >>> import pipeclient
+
+    # Create a client instance:
+    >>> client = pipeclient.PipeClient()
+
+    # Send a command:
+    >>> client.write("Command", timer=True)
+
+    # Read the last reply:
+    >>> print(client.read())
+
+See Also
