I have a VERY simple application that refuses to start.
This is the error trace:
pi@raspberrypi:~/Projects/HelloWorld $ python3.5m main.py

if __name__ == '__main__':
cherrypy.quickstart(HelloWorld(), '/', 'main.conf')
*main.conf:*

Truetools.staticdir.dir = './html',tools.staticdir.index =
'index.html'[/css]tools.staticdir.on = Truetools.staticdir.dir = './css'*
If I leave only the [global] section in the conf file then the application
starts.
So it seems something is wrong with the [/] and onwards part.
But what ? Any ideas ?
