Added README file. Please note most webcams require isochronous support,

so you'll have to wait for Haiku's USB to support them anyway,
as R5 nor Zeta's really grock iso.

+USB Webcam driver
+(c) 2004,2005,2006 François Revol.
+
+Current version of my USB Webcam driver. WORK IN PROGRESS!
+Uses the USB Kit (userland API, needs libusb) to publish a
+media node representing the webcam.
+
+It currently only works with my Sonix webcam (3Euro cheapo
+cam), but is modular enough to easily expand it, some code
+is already there to detect Quickcams.
+
+Note however that most webcams only support isochronous 
+transfers, so will NOT work in R5 or even Zeta as isochronous 
+is mostly not working. That's the reason for only supporting
+my Sonix webcam as it is bulk capable.
+As soon as iso support is added to the USB stack and the 
+USB Kit it should be possible to support other webcams quite 
+easily.
+
+For now you should be able to build it under Zeta with the
+makefile provided.
+
+Making a Jamfile might get tricky as several source files are
+created by the makefile itself to include addons and censors
+in the build.
