+ (description "This module provides a convenient way to perform cleanup or
+other forms of resource management at the end of a scope. It is particularly
+useful when dealing with exceptions: the Scope::Guard constructor takes a
+reference to a subroutine that is guaranteed to be called even if the thread
+of execution is aborted prematurely. This effectively allows lexically-scoped
+\"promises\" to be made that are automatically honoured by perl's garbage
+collector.")
