+/*
+ * Driver for Alauda-based card readers
+ *
+ * Current development and maintenance by:
+ *   (c) 2005 Daniel Drake <dsd@gentoo.org>
+ *
+ * The 'Alauda' is a chip manufacturered by RATOC for OEM use.
+ *
+ * Alauda implements a vendor-specific command set to access two media reader
+ * ports (XD, SmartMedia). This driver converts SCSI commands to the commands
+ * which are accepted by these devices.
+ *
+ * The driver was developed through reverse-engineering, with the help of the
+ * sddr09 driver which has many similarities, and with some help from the
+ * (very old) vendor-supplied GPL sma03 driver.
+ *
