- expat library; git-http-push uses it for remote lock
management over DAV. Similar to "curl" above, this is optional.
- - "GNU diff" to generate patches. Of course, you don't _have_ to
- generate patches if you don't want to, but let's face it, you'll

- Non-GNU versions of the diff/patch programs don't generally support
- the unified patch format (which is the one git uses), so you
- really do want to get the GNU one. Trust me, you will want to
- do that even if it wasn't for git. There's no point in living
- in the dark ages any more.
