TODO: Use it to re-running ccamftp.php see if any arguments are provided. If they are - they are bit number, sleep time in seconds and command/arguments of an external program to be launched. Usually - a php script, so it makes sense not to keep the php instance in memory if it is not used most of the time (done so for ccamftp.php)

Daemon loop - waiting for being enabled, run autocampars.php NOTE: Requires sequencers and sensor to be running, to reset everything if stuck - use autocampars.php directly

wait for autoexposure daemon to be enabled (let it sleep if not)

do we need any fork at all if we now serve images to one client at a time?

We do not need to pass any parameters here, but if we had to - first argument is lost (probably to "-q" in the script line 1

comes here only if error

skip 1 frame before returning
