zodbcmp - Tool to compare two ZODB databases

This is a tool to compare two ZODB databases in between tidmin..tidmax
transaction range with default range being -∞..+∞ - (whole database).

For comparision both databases are scanned at storage layer and every
transaction content is compared bit-to-bit between the two. The program stops
either at first difference found, or when whole requested transaction range is
scanned with no difference detected.

Database storages are specified in files with ZConfig-based storage definition, e.g.

    %import neo.client
    <NEOStorage>
        master_nodes    ...
        name            ...
    </NEOStorage>

Please see https://lab.nexedi.com/nexedi/neoppod/merge_requests/4 for
one of possible contexts.

The tool is generic though and is not NEO-specific. It should be able to
even check two different storages like ZEO & NEO, or FileStorage and NEO
etc and thus can be handy.
