+==================
+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.

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

+was not ported to Linux 2.6 (yet).
+
+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.
