log_warn("Forked in to background PID $pid");
$SIG{__WARN__} = \&log_warn;
$SIG{__DIE__} = \&log_die;
for my $cid (1..4) {
my $child = launch_child();
if ($child == 0) {
log_warn("I am child PID $$") while sleep 2;

kill_children();DESCRIPTION
Proc::DaemonLite is a basic server daemonisation module that trys to cater for most basic Perl daemon requirements.
The POD for this module is incomplete, as is some of the tidying of the code. It is however fully functional. This is a pre-release in order to reserve the namespace before it becomes unavailable.
