git user's manual

I'm still tinkering with this "Git User's Manual"; you can see the current draft at:

	http://fieldses.org/~bfields/git-user-manual.html

or get the source from the branch master in:

	git://linux-nfs.org/~bfields/git.git

Changes include:

	- a "quick start" with a bunch of commands and no explanation,
	  as the first chapter
	- discussion of git-remote, presenting that as the primary
	  method for tracking remotes and postponing fetches of
	  individual branches till later.  (Is this a sensible
	  approach?)
	- import of a slightly modified version of the README as the
	  start of a "git internals' chapter.
	- discussion of history rewriting, pitfalls thereof,
	  cherry-pick, rebase, etc.
	- updates to try to track recent interface improvements,
	  etc.

So it's longer, but still incomplete, and some of it's probably quite wrong....

Despite that I'm tempted to ask that it be merged some time soon and just not referred to much yet; then hopefully people could help bludgeon it into shape before we start adding pointers to it from elsewhere.

Then we'll have to figure out whether it could obsolete any existing documentation. I'd kind of like to rip out tutorial-2.txt at least, and maybe absorb cvs-migration and a few other things as new chapters.

I dunno; thoughts?
