------------------------------------
Installation of gitweb behind NGINX,
using spawn-cgi and fcgiwrap
------------------------------------

You need to run the script as root, there is no way all of this will install as normal user :P

Options:
 
  -h  : show this message
  -n  : install the default nginx package
  -f  : omits the install spawnfcgi to spawn fcgi processes (if you have another spawner, it's fine)
  -s  : omits the installation of fcgiwrap (needed for nginx)
  -t  : omits the github theme for gitweb, using the default theme (github theme by kogakure, http://github.com/kogakure/gitweb-theme)

******************************

Installation OK!

Next steps:
-----------
spawn an instance of spawn-fcgi (or your own, change settings if you need):
  spawn-fcgi -f /usr/local/sbin/fcgiwrap -a 127.0.0.1 -p 9001

update the nginx server configuration:

  server {
      listen 80;
      server_name yourdomain.com;

      location / {
          root /usr/share/gitweb;
          if (!-f \$request_filename) {
              fastcgi_pass   127.0.0.1:9001;
          }
          fastcgi_index  index.cgi;
          fastcgi_param  SCRIPT_FILENAME  /usr/share/gitweb/gitweb.cgi;
          include        fastcgi_params;
      }
  }

update the gitweb.conf file (located by default in /etc/gitweb.conf):

The extra theme has copied the old css file for safety to .old in the /usr/share/gitweb/static folder :)
