-        tristate "Texas Instruments parallel link cable support"
-        depends on PARPORT
-        ---help---
-          If you own a Texas Instruments graphing calculator and use a
-          parallel link cable, then you might be interested in this driver.
-
-          If you enable this driver, you will be able to communicate with
-          your calculator through a set of device nodes under /dev. The
-          main advantage of this driver is that you don't have to be root
-          to use this precise link cable (depending on the permissions on
-          the device nodes, though).
-
-          To compile this driver as a module, choose M here: the
-          module will be called tipar.
-
-          If you don't know what a parallel link cable is or what a Texas
-          Instruments graphing calculator is, then you probably don't need this
-          driver.

-/* Hey EMACS -*- linux-c -*-
- *
- * tipar - low level driver for handling a parallel link cable designed
- * for Texas Instruments graphing calculators (http://lpg.ticalc.org).
- * A part of the TiLP project.
- *
- * Copyright (C) 2000-2002, Romain Lievin <roms@lpg.ticalc.org>
- * under the terms of the GNU General Public License.
- *
- * Various fixes & clean-up from the Linux Kernel Mailing List
- * (Alan Cox, Richard B. Johnson, Christoph Hellwig).
- */
-
-/* This driver should, in theory, work with any parallel port that has an
- * appropriate low-level driver; all I/O is done through the parport
- * abstraction layer.
- *
- * If this driver is built into the kernel, you can configure it using the
- * kernel command-line.  For example:
- *
- *      tipar=timeout,delay       (set timeout and delay)
- *
- * If the driver is loaded as a module, similar functionality is available
- * using module parameters.  The equivalent of the above commands would be:
- *
- *      # insmod tipar timeout=15 delay=10
- */
-
-/* COMPATIBILITY WITH OLD KERNELS
- *
- * Usually, parallel cables were bound to ports at
- * particular I/O addresses, as follows:
- *
- *      tipar0             0x378
- *      tipar1             0x278
- *      tipar2             0x3bc
- *
- *
- * This driver, by default, binds tipar devices according to parport and
- * the minor number.
