[Zope-dev] Heads up -- big changes on trunk

[Chris McDonough]

Additionally, other mass changes to the trunk will occur when Andreas merges
the work he's done to rid the codebase of "regex" in favor of "re".

One of the more major shifts is the deprecation of the "old" structured text
in favor of StructuredTextNG, which is serviced via a compatibility module.
The compatibility module is known to break the Zope Tutorial product
currently, but everything else in the core that uses StructuredText (e.g.
dtml-var fmt=structured-text and the help system) seems to work well.  The
tutorial will work again once 2.4 final is released.
