However, there's other portlets BBB related to the way
_prepare_slots() (called from globalize()) defines variables which are
then checked by tal:condition statements in main_template. If you have
a customised main_template, you're probably using these (variables
'sl' and 'sr') at *least* to determine whether left slots and right
slots should be shown.
Fixing your template to use the new portlets stuff is easy (you
probably only need a content provider; we may also want some more sane
names for the "showLeftPortlets" and "showRightPortlets" variables).
The current code attempts to do BBB, but has no real tests to prove
that it actually works. :)
