IO::ReStoreFH Redirecting and restoring I/O streams is straightforward but a chore, and can lead to strangely silent errors if you forget to restore STDOUT or STDERR. IO::ReStoreFH helps keep track of the present state of filehandles and low-level file descriptors and restores them either explicitly or when the IO::ReStoreFH object goes out of scope.
