-// The tomb package offers a conventional API for clean goroutine termination.
-//
-// A Tomb tracks the lifecycle of a goroutine as alive, dying or dead,
-// and the reason for its death.
-//
-// The zero value of a Tomb assumes that a goroutine is about to be
-// created or already alive. Once Kill or Killf is called with an
-// argument that informs the reason for death, the goroutine is in
-// a dying state and is expected to terminate soon. Right before the
-// goroutine function or method returns, Done must be called to inform
-// that the goroutine is indeed dead and about to stop running.
-//
-// A Tomb exposes Dying and Dead channels. These channels are closed
-// when the Tomb state changes in the respective way. They enable
-// explicit blocking until the state changes, and also to selectively
-// unblock select statements accordingly.
-//
-// When the tomb state changes to dying and there's still logic going
-// on within the goroutine, nested functions and methods may choose to
-// return ErrDying as their error value, as this error won't alter the
-// tomb state if provided to the Kill method. This is a convenient way to
-// follow standard Go practices in the context of a dying tomb.
-//
-// For background and a detailed example, see the following blog post:
-//
-//   http://blog.labix.org/2011/10/09/death-of-goroutines-under-control
-//
-// For a more complex code snippet demonstrating the use of multiple
-// goroutines with a single Tomb, see:
-//
-//   http://play.golang.org/p/Xh7qWsDPZP
