Readme for repa-v4l2-0.2.0.0

[back to package description] 
Provides high-level access to webcams for Haskell programs.

The current state is that the library provides a monad for
grabbing images from a webcam under Linux. In the future, more functionality like 
image processing functions and other input devices may be added.

Last time I checked, the v4l2 package was not on hackage, 
but it can be retrieved from here:
 https://gitorious.org/hsv4l2

For images, repa arrays are used. Therefore, all the repa goodness
can be used with the data. It should also be possible without too much hassle 
to write a function which gets the data into a different type of array,
if that is necessary.

Getting an image with a v4l webcam works like this:

> import Graphics.Webcam.Linux
> main = runCam (grab >>= saveBmp "my_image.bmp") (Webcam 0)
