Everyday: a bit more examples.
Talk about the following as well: * git fetch --tags * Use of "git push" as a one-man distributed development vehicle. * Show example of remotes file for pulling and pushing. * Annotate git-shell setup. * Using Carl's update hook in a CVS-style shared repository. Signed-off-by: Junio C Hamano <junkio@cox.net>
