[GRLUG] git 'snapshots'

[Eric Beversluis]

I'm doing some reading about git and I'm confused by their 'snapshots.'
Several things that I've read all seem to say that git doesn't use diffs
but rather uses snapshots. If they don't use diffs, it seems to me that
the snapshot must be the entire document, each time you commit. Yet it
also seems to claim small size and high speed, with all the branches and
versions on your local computer. I don't see how this can be.
