CGIT is a nice, quick, and easy way of displaying git repositories. After much fighting I figured out how to allow CGIT to display URLs such as http://code.example.com/repository.git (the git is optional).

Below is the Apache config for code.example.com:

<VirtualHost *:80>
    ServerName code.example.com
    DocumentRoot /var/www/code.example.com
    CustomLog logs/code.example.com.access_log combined
    ErrorLog logs/code.example.com.error_log
    SetEnv CGIT_CONFIG          /var/www/code.example.com/cgitrc
    Alias /cgit.css             /var/www/code.example.com/cgit.css
    Alias /cgit.png             /var/www/code.example.com/cgit.png
    Alias /favicon.ico          /var/www/code.example.com/favicon.ico
    Alias /robots.txt           /var/www/code.example.com/robots.txt
    Alias /                     /var/www/code.example.com/cgit.cgi/
    <Directory /var/www/code.example.com>
      Options Indexes FollowSymLinks
      Options +ExecCGI
      Order allow,deny
      Allow from all
      AddHandler cgi-script .cgi
      DirectoryIndex cgit.cgi
    </Directory>
</VirtualHost>
