* Add parameter crontab:use_sudo to allow running crontab using sudo.
This makes it possible to overwrite the bin/crontab variable to edit crontab for other users.
e.g.
set("crontab:use_sudo", true);
set("bin/crontab", function () {
return which('crontab') . " -u www-data";
});
* Add documentation and use cases for crontab:use_sudo
* Regenerate documentation with docgen
