3   FlashPoint.c -- FlashPoint SCCB Manager for Linux
4 
5   This file contains the FlashPoint SCCB Manager from BusLogic's FlashPoint
6   Driver Developer's Kit, with minor modifications by Leonard N. Zubkoff for
7   Linux compatibility.  It was provided by BusLogic in the form of 16 separate
8   source files, which would have unnecessarily cluttered the scsi directory, so
9   the individual files have been combined into this single file.
