-=head1 NAME
-
-SDL::Timer - a SDL perl extension to handle timers
-
-=head1 SYNOPSIS
-
-  $timer = new SDL::Timer { print "tick"; 4000; } -delay => 4000;
-
-=head1 DESCRIPTION
-
-C<SDL::Timer> provides an abstract interface to the SDL::Timer
-callback code.  SDL::Timer::new requires a subroutine and a delay
-at which is the initial interval between the creation of the
-timer until the first call to the subroutine.  The subroutine
-must return a value which is the delay until the it is called again.
