Re: [PATCH] Adding Correct Useage Notification and -h Help flag

Heres the revised patch along the lines you recommended yesterday. I am
still working on some of the command descriptions.

On the git-update-cache question, I think having a flag [-u] or
something like that in git commit would allow the user to decide to run
git-update-cache on only the files specified in the git commit command.

Make the git wrapper a little bit more newbie friendly, when called on its own or with the -h flag will return a list of the commands available
