[cups] How to call a script when a job arrives

[Kurt Pfeifle]

Have a look like tea4cups, beh (back end handler of cups-filters by
OpenPrinting) or papercut handle similar problems. Basically, they are
wrappers around the real backends. They re-define the original URIs as
"beh:socket://address" or "papercut:ipp://..." or
"tea4cups://lpd://address". When called, they do their thing and after
finishing just invoke the original backend with the original (or modified)
parameters.

So your script could be called "curl", hooked into CUPS as
"curl:[optional_params]socket://address" similar to "beh" (see example
usage at
https://github.com/OpenPrinting/cups-filters/blob/5e6695a94e1a24b66cac9fe8e39c41571e08971d/README#L1541
)
