annotate roundup/cgi/MultiMapping.py @ 2119:cc4667ef3f12
Added the ability to toggle where error messages go.
They either go to the user (default, for backwards compatibility), the
dispatcher, or both. These are able to be toggled via settings in config.py.
Please refer to upgrading.txt for more details. (And Richard, let me know
if I've done anything wrong with this checkin. :))
