// Package resumable registers resumable versions of hash functions. Resumable
// varieties of hash functions are available via the standard crypto package.
// Support can be checked by type assertion against the resumable.Hash
// interface.
//
// While one can use these sub-packages directly, it makes more sense to
// register them using side-effect imports:
//
// import _ "github.com/stevvooe/resumable/sha256"
//
// This will make the resumable hashes available to the application through
// the standard crypto package. For example, if a new sha256 is required, one
// should use the following:
//
// h := crypto.SHA256.New()
//
// Such a features allows one to control the inclusion of resumable hash
// support in a single file. Applications that require the resumable hash
// implementation can type switch to detect support, while other parts of the
// application can be completely oblivious to the presence of the alternative
// hash functions.
//
// Also note that the implementations available in this package are completely
// untouched from their Go counterparts in the standard library. Only an extra
// file is added to each package to implement the extra resumable hash
// functions.
