This thresholding example is the perfect occasion to introduce my
latest joke project, cclambda. With cclambda, everything is in
the command-line!

  ./cclambda - "(A < .5 ? 0 : A)" < data/lena.png > out.png

And you can compose multiple one-liners with shell pipes.

123 lines of C code, 22 lines for the shell wrapper (plus the 800 lines
for io_png, plus libpng, of course).

I don't want cclambda to give headaches to anyone. It's an
über-experimental joke project dumped from my brain in an
afternoon. Don't use it!
