Generate and maintain a checksum file using the specified message

.Pa \&.DIGEST.CHECKSUMS

A checksum check is done on each file of the destination when the destination
appears to be the same as the source. If the check fails,
the source is recopied to the destination. When you specify a destination
directory, the checksum file is only updated as needed and may not be updated
even if modifications are made to a source file. If you do not specify a
destination directory the
.Nm
command forcefully regenerates the checksum for every file in the source.
