How to set up a streaming webcam
--------------------------------

Compile cqcam as usual (see INSTALL for details).  Put the 'webcam' binary
in /usr/local/bin, and make it SUID root.  'make install' will do this for
you.  Copy the 'nph-webcam' script to your cgi-bin directory.  Copy the
webcam.html page to your htdocs directory.  Make sure your web server has
been started.  At this point,
  http://localhost/webcam.html
should produce a bare-bones page with a streaming picture on it.  You'll
get a few auto-updated frames.  Click 'reload' for a few more.

I am told that this doesn't work with IE, though I have no desire to
verify this fact.  If you want streaming images, get a real browser. 


How to tweak it
---------------

Set up a better page.  webcam.html is just a sample.  The tag
  <img src="/cgi-bin/nph-webcam">
will put a streaming image into any normal page.  The 'alt', 'width',
and 'height' modifiers to the 'img' tag will work fine and are highly
recommended.

You can change the location of the webcam binary, the options passed to
it, and the headers passed to the client in the nph-webcam script.
Customization of the webcam binary itself is done through config.mk at
compile time.  See INSTALL for details.

This documentation is probably inadequate.  Forward me any questions or
suggestions, and I'll update it.
