Hello Nigel,

Please have a look at the scripts that came with the post that started
this thread. Do you have any reason to assume that these "rsync hashes"
can be more efficient than the deltas generated by Mike's script?

By the way, minigzip.c comes with the zlib-devel rpm
(/usr/share/doc/zlib-devel-<version>).

$ gcc minigzip.c -lz -o minigzip

Bye,
Leonard.
