NIH roundup: EPI, Jinja, paste...profile, zcatalog, ZODB

This past week I've moved up the stack from Aspen, and have been working on a skunkworks project in which I'm experimenting with:

• ExtendedPathIndex--This is a hack from Helge Tesdal to make generating navigation structures from a Zope catalog much easier.
  
• Jinja--Tantamount to stand-alone Django templates; a good effort, though the documentation needs some polish (both in terms of accuracy and English), and it is cutting my req/sec by 80%.
• paste.debug.profile--I finally bit the bullet and installed paste, rather than trying to use modules piecemeal. This middleware almost worked without change: the trunk version has a niggling Python 2.5 dependency. Once working, it's great!
• zcatalog--Back before Kevin Dangoor started TurboGears, he hacked up this standalone version of the Zope 3 catalog. The big drawback is that the most recent documentation is for Zope 2.7. My copy of Phillip's book only says that "[t]he successor to the famous Zope Catalog [is] still being developed." Use the source, Luke!
• ZODB--I have a very high view of the ZODB: MVCC and BTrees seem so manly, and once you find it, ZODB has the best documentation in all of Zope.

So how's that for NIH! Feed back to Chad Whitacre.
