NAME
       "IO::Async::Signal" - event callback on receipt of a POSIX signal

SYNOPSIS
          use IO::Async::Signal;

          use IO::Async::Loop;
          my $loop = IO::Async::Loop->new;

          my $signal = IO::Async::Signal->new(
             name => "HUP",

             on_receipt => sub {
                 print "I caught SIGHUP\n";
             },
          );

          $loop->add( $signal );

          $loop->run;

DESCRIPTION
       This subclass of IO::Async::Notifier invokes its callback when a
       particular POSIX signal is received.

       Multiple objects can be added to a "Loop" that all watch for the same
       signal.  The callback functions will all be invoked, in no particular
       order.

EVENTS
       The following events are invoked, either using subclass methods or CODE
       references in parameters:

   on_receipt
       Invoked when the signal is received.

PARAMETERS
       The following named parameters may be passed to "new" or "configure":

   name => STRING
       The name of the signal to watch. This should be a bare name like
       "TERM". Can only be given at construction time.

   on_receipt => CODE
       CODE reference for the "on_receipt" event.

       Once constructed, the "Signal" will need to be added to the "Loop"
       before it will work.
