// Package tarsum provides algorithms to perform checksum calculation on
// filesystem layers.
//
// The transportation of filesystems, regarding Docker, is done with tar(1)
// archives. There are a variety of tar serialization formats [2], and a key
// concern here is ensuring a repeatable checksum given a set of inputs from a
// generic tar archive. Types of transportation include distribution to and from a
// registry endpoint, saving and loading through commands or Docker daemon APIs,
// transferring the build context from client to Docker daemon, and committing the
// filesystem of a container to become an image.
//
// As tar archives are used for transit, but not preserved in many situations, the
// focus of the algorithm is to ensure the integrity of the preserved filesystem,
// while maintaining a deterministic accountability. This includes neither
// constraining the ordering or manipulation of the files during the creation or
// unpacking of the archive, nor include additional metadata state about the file
// system attributes.
