Simple Groupware nginx config

[Mark Alan]

In case anyone needs to setup Simple Groupware
http://www.simple-groupware.de/  (it is a web-based groupware that
offers email, calendaring, contacts, tasks, document management,
project management, synchronization with Outlook and cell phones,
full-text search, extensions, etc),
using Debian 6 / Ubuntu 11.10 and Nginx 1.1.12,

here is the config file provided by Simple Groupware's leader & main
developer:

(ED: it works, but it must be one of the ugliest Nginx config files that
we have seen)

# nginx - /etc/nginx/sites-available/sgw
server {
	listen 80;
	server_name sgw.localhost;
	#root sgw; # TODO change to Simple Groupware root directory
	access_log /var/log/nginx/sgw.access.log;
	error_log /var/log/nginx/sgw.error.log;
	root /var/www/sgw;
	#index index.php;

	location / {
