zope.documenttemplate is a crippled version of DocumentTemplate. It
doesn't have all features (e.g. it lacks the C extension module) and
hasn't been kept up-to-date with respect to bugfixes. So it seems like
a good idea to put this clone out of its misery and retire it.
I ultimately suggest going to absolute imports everywhere (at least as
long as we have to maintain Python 2.4 compatibility). I realize that
DocumentTemplate/DocumentTemplate.py creates a problem. So here's what
I suggest:
1. Rename DocumentTemplate/DocumentTemplate.py to, say,
DocumentTemplate/DocTemplate.py (feel free to come up with
a better name)
2. Introduce absolute imports to DocumentTemplate.DocTemplate
everywhere
3. Ensure backwards compatibility by adding the following lines
to DocumentTemplate/__init__.py::
import DocumentTemplate.DocTemplate
import sys
sys.modules['DocumentTemplate.DocumentTemplate'] =
DocumentTemplate.DocTemplate
I *think* this should work.
