## Description
This program calculates and print specified checksum of files. It cannot be run directly, only
as `md5sum`, `sha1sum`, `sha256sum` or `sha512sum`. A non-zero exit code is returned if the
as `b2sum`, `md5sum`, `sha1sum`, `sha256sum` or `sha512sum`. A non-zero exit code is returned if the
input cannot be read. If the '--check' option is used, a non-zero exit code is also returned
if the checksums cannot be verified.
