A friend of mine made me aware of a nicer web interface for git than gitweb called cgit. You will need to grab the source and compile it. I am assuming that you use /var/www/ as the root of your web server and fcgiwrap which should be configured right already. This is the missing bits for my config:

       location /cgit/ {
		index cgit.cgi;
		include fastcgi_params;
                gzip off;

               if ($uri ~ "/cgit/cgit.cgi") {
                        fastcgi_pass unix:/var/run/fcgiwrap.socket;
                }

        }

You then need to create a folder called /var/www/cgit in which you copy the cgit binary but also cgit.css and cgit.png. You then need to create a /etc/cgitrc configuration file which you will edit for your local configuration and projects. Mine looks like this:

root=/var/cache/git
repo.url=tripwire
repo.desc=Tripwire
repo.path=/var/cache/git/tripwire/.git

Restart/reload your nginx and you are ready to roll.
