	  d impl.go
		Package impl is a registry of alternative implementations of cryptographic
		primitives, to allow selecting them for testing.
Package-Level Functions (total 4)

	 func List(pkg string) []string
		List returns the names of all alternative implementations registered for the
		given package, whether available or not. The implicit base implementation is
		not included.

	 func Register(pkg, name string, available *bool)
		Register records an alternative implementation of a cryptographic primitive.
		The implementation might be available or not based on CPU support. If
		available is false, the implementation is unavailable and can't be tested on
		this machine. If available is true, it can be set to false to disable the
		implementation. If all alternative implementations but one are disabled, the
		remaining one must be used (i.e. disabling one implementation must not
		implicitly disable any other). Each package has an implicit base
		implementation that is selected when all alternatives are unavailable or
		disabled. pkg must be the package name, not path (e.g. "aes" not "crypto/aes").

	 func Reset(pkg string)
	 func Select(pkg, name string) bool
		Select disables all implementations for the given package except the one
		with the given name. If name is empty, the base implementation is selected.
		It returns whether the selected implementation is available.
