+Goal of branch
+==============
+
+To test traversal without archive folders.  
+
+NOT FOR PRODUCTION USE!!!
+
+
+Base
+====
+
+I (Maurits van Rees) copied revision 32362 of the Quills trunk.
+
+
+Problem
+=======
+
+When you publish a weblog entry, that entry is moved to
+e.g. weblog/archive/2006/11/10/entry-id.  It is said that whenever you
+move an object during a workflow transition, cats start disappearing
+mysteriously.  Not good.
+
+Also, personally I would want that entry to appear as
+weblog/2006/11/entry-id, so without 'archive' and without the day.
+The last part is pretty doable; it just means changing the
+createPath() method in WeblogArchive.py.  Before I started throwing
+traversal code around, that part seemed to work fine, so if you're
+just looking for that, you could monkey patch WeblogArchive in your
+own product.
+
+In general, some more flexibility in those folders would be useful.
+
+
+Strategy
+========
+
+Several people seems to think it is a good idea to just put all weblog
+entries in one BTreeFolder.  So we want to get rid of WeblogArchive.
+Instead of that we make an archive.py which is used by traversal.py to
+fake a temporary folder structure.  When you type weblog/2006/11 in
+your browser, a catalog query should be done for all weblog entries
+that were posted in November 2006.
+
+
+
+Status
+======
+
+- Completely broken!  When I add a weblog entry, that entry is made,
+  but I am never given a chance to edit it.  Probably there is
+  something very wrong with traversal now.
+
+- At some points I am simply returning an empty list or False or None
+  as an answer instead of actually trying to come up with a good
+  answer.  
+
+- When you go to e.g. weblog/2006 you will see a message: "no entries
+  published yet" or something to that effect.  This is good and shows
+  that traversal is somewhat okay.
+
+
+Plans
+=====
+
+I am hacking and slashing wildly in a product I don't know that well
+yet.  This doesn't look like something I can pull off on my own.  But
+at least the code is out in the open now, so others can chip in.  The
+next step is up to others.
+
+Feel free to take over this branch.  The major files to look at are
+traversal.py and archive.py, which is intended as a replacement for
+WeblogArchive.py
+
+
+Other approaches
+================
+
+You may want to look at two other branches that try something similar:
+
+http://dev.plone.org/collective/browser/Quills/branches/tvon-flat-btree-weblog
+
+and
+
+http://dev.plone.org/collective/browser/Quills/branches/tvon-traversal-based-weblog-views-branch
+
+Also, there is a more general Zope 3 approach which may be a better
+path to take:
+
+svn://svn.zope.org/repos/main/z3c.traverser/trunk
+
+I don't think Quills is the only product that wants something like
+this, so a more general approach may be the best way to get more
+developers on board.
+
+
+One unspecified goal of this branch has been met: I had fun coding. :)
