+ This backend is based upon the Tamarack backend and adapted to the Avision
+ scanners by René Rebe and Meino Cramer.
+
+ This file implements a SANE backend for the Avision SCSI Scanners (like the
+ AV 630 / 620 (CS) ...) and some Avision (OEM) USB scanners (like the HP 53xx,
+ 74xx, Minolta FS-V1 ...) or Fujitsu ScanPartner with the AVISION SCSI-2/3
+ or USB command set.
