------------------------------------------
developers only! this game is currently not playable!

main.py is the main script. call this from a browser.

the init_webgo.main() in main.py reinitializes the whole database on each call, so
comment the line out if you do not want that. init_webgo also creates two test users,
gast and gast2. password = username. you can use those to log in.
------------------------------------------
want to create your own goban images? Simple: just replace the images in 
imgsource/ with the desired ones. then run generate_goban_images.py and 
the new images get written to img/.
------------------------------------------
overview of the files:
main.py        - the main script. Essentially a wrapper that prints the 
                 traceback if something went wrong.
login.py       - this file contains functions for login and game 
                 selection/modification.
goban.py       - code for displaying a goban as a html page.
psql.py        - all functions directly accessing the database.
init_webgo.py  - re-initialize the whole game. deletes everything and 
                 sets some defaults.
helper.py      - small functions for string manipulation etc.
generate_goban_images.py
               - recreate the goban images. just run from console.

------------------------------------------
coding guidelines
tab == 4 whitespaces.
function names are lowercase with _ as a seperator.
------------------------------------------
some code snippets for reference:


How to make the goban clickable:
	data += '<form method="post">'
	data += '<input type=image src="img/bottomrightline.png" name="untenrechts">'
	#insert rest of goban here
	data += '</form>'
	print data

How to extract the data from this POST with the cgi module:
	import cgi
	#get instance of fieldstorage
	form = cgi.FieldStorage()
	#if form == empty (which means if page is displayed for the first time):
	if form.keys() != []:
		#cut out the name of the clicked button
		print string.split(form.keys()[0],".x")[0]
