+/*
+ *	Interface for other generic SCSI implementations.
+ *	Emulate the functionality of /dev/usal? with the local
+ *	SCSI user land implementation.
+ *
+ *	To add a new hack, add something like:
+ *
+ *	#ifdef	__FreeBSD__
+ *	#define	SCSI_IMPL
+ *	#include some code
+ *	#endif
+ *
+ *	Warning: you may change this source or add new SCSI tranport
+ *	implementations, but if you do that you need to change the
+ *	_usal_version and _usal_auth* string that are returned by the
+ *	SCSI transport code.
+ *	Choose your name instead of "schily" and make clear that the version
+ *	string is related to a modified source.
+ *	If your version has been integrated into the main steam release,
+ *	the return value will be set to "schily".
