299
300	  This driver is a replacement for (and was inspired by) an older

323
324	  This driver is a light version of i2c-parport.  It doesn't depend
325	  on the parport driver, and uses direct I/O access instead.  This
326	  might be prefered on embedded systems where wasting memory for
327	  the clean but heavy parport handling is not an option.  The
