There are a few quite innocent things that occur during routine transfers
that work havoc on checksums - line ending sequences, tab expansions, and
end-of-line whitespace pruning.

These can be handled (generally by carrying the code around in a bottle of
some kind - tar, zip, etc) once one is aware of the issue.
