[Grok-dev] Re: Grokinstallation corrupts when editing source remotely over AFP

Wed Jun 11 11:23:06 EDT 2008

I edited app.py, adding some simple arithmetic to an update method  
(the first three lines):

       def update(self):
         a= 1
         b = 2
         c = a + b
         protoncms.protonbase.ProtonEdit.update(self)
