/*
My Super Duper Webcam Interface.
wrote it once, lost it, wrote it again.
So, this is version 2.0

What it does?
Sucks a jpeg from stdout that was spewed
by clcam. (see: sourceforge for the project)
sticks a caption on it, saves it in a cache dir.

    When the camera is "busy" it spews a previously
cached image.

    It all currently works with php4 point anything
GD is required, and a ttf font file of your choice.

    But, really, lets face it I'm not gonna dress it up
all pretty.  We're not going to the prom.

    So, use it if you want. It's fairly straight forward.
