Hi Dan,

I don't want to introduce a dependency on twiddler or genshi into  
CMFCalendar and it's not necessary for this as the template requires  
little or no logic: formatting or string.Template are more than  
adequate but I would like to have the template outside of the calling  
script. You can in fact use ZPT quite well for non *ML if you use the  
pseudo-tags
<tal:content tal:content="options/start_date" /> is only a little bit  
more verbose than %(start_date)s or $start_date but it would be nice  
to have a handler for string.Template templates. Is it possible to  
work with .txt?

ie.
template = context.event_ics_template()
template = template % options # or template.substitute(options)

The bigger problem seems that there is no easy way to get the  
timezone needed to get appointments to work properly. vCal requires  
timezone id's like Europe/Amsterdam. Looks like the only thing is to  
coerce the time to what the server thinks is UTC and hope the client  
will do the conversion.
