		This driver is DEPRECATED please use the gspca ov519 module
		instead. Note that for the w9968cf support of the gspca module
		you need atleast version 0.6.3 of libv4l.

		Say Y here if you want support for cameras based on OV681 or
		Winbond W9967CF/W9968CF JPEG USB Dual Mode Camera Chips.

		This driver has an optional plugin, which is distributed as a
		separate module only (released under GPL). It allows to use higher
		resolutions and framerates, but cannot be included in the official
		Linux kernel for performance purposes.

		See <file:Documentation/video4linux/w9968cf.txt> for more info.

		To compile this driver as a module, choose M here: the
		module will be called w9968cf.
