There is no so called framework and algorithm, the snapshot object is
just a sha1 copy of object organized by a trunk structure, which is
indexed by a sha1 string.

I think the code is just less than 1k lines, not that hard to
understand, so simply run and read the code to get the idea if you think
farm-internal.txt doesn't explain any confusion to you.
