Michel's use of a debug flag is cool. Only, are you aware of Z_DEBUG_MODE
(aka BOBO_DEBUG_MODE, aka __bobo_debug_mode__)? It's purpose is exactly
things like this. It gives more informative errors, and should make all
objects that care operate in debug mode.

For example, I believe that HTMLFiles should check for this and reload it's
content if it is set.

Check out this snippet of code from Main.py

for n in 'Z', 'BOBO':
    if os.environ.has_key('%s_DEBUG_MODE' % n):
        n=string.lower(os.environ['%s_DEBUG_MODE' % n])
        if n=='no' or n=='off': continue
        try: n=string.atoi(n)
        except: pass
        if n: Globals.DevelopmentMode=1 

Now you know how to check for debug mode in your own objects, check for
'DevelopmentMode'
