+==================
+i2c-parport driver
+==================
+
+2004-07-06, Jean Delvare
+
+This is a unified driver for several i2c-over-parallel-port adapters,
+such as the ones made by Philips, Velleman or ELV. This driver is
+meant as a replacement for the older, individual drivers:
+ * i2c-philips-par
+ * i2c-elv
+ * i2c-velleman
+ * video/i2c-parport (NOT the same as this one, dedicated to home brew
+ teletext adapters)
+
+It currently supports the following devices:
+ * Philips adapter
+ * home brew teletext adapter
+ * Velleman K8000 adapter
+ * ELV adapter
+ * Analog Devices evaluation boards (ADM1025, ADM1030, ADM1031, ADM1032)
+
+These devices use different pinout configurations, so you have to tell
+the driver what you have, using the type module parameter. There is no
+way to autodetect the devices. Support for different pinout configurations
+can be easily added when needed.
+
+
+Building your own adapter
+-------------------------
+
+If you want to build you own i2c-over-parallel-port adapter, here is
+a sample electronics schema (credits go to Sylvain Munaut):

+This driver is NOT the same as the i2c-pport driver found in the i2c package.

+
+This driver is also NOT the same as the i2c-pcf-epp driver found in the
+lm_sensors package. The i2c-pcf-epp driver doesn't use the parallel port
+as an I2C bus directly. Instead, it uses it to control an external I2C bus
+master. That driver was not ported to Linux 2.6 (yet) either.

+ LIBK8000 v1.99.1 and LIBK8005 v0.21
+With these libs, you can control the K8000 interface card and the K8005

+many more, using /dev/velleman.
