Re: Import speed issue

Hi Brian,
the Cheetah.Template module has a lot of depencies and it simply takes a while 
to load them all.  If you're using Cheetah with WebKit then you should be 
aware that only the initial import will show this delay.   Python caches 
imported modules and thus this initial import time doesn't really affect long 
running processes like WebKit.
Cheers,
Tavis
