(synopsis "Lexically-scoped resource management")
(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.")
