Here are my programs, patches, examples and all that. Enjoy!
mod_pcgi2 - An Apache module for Zope/PCGI. The module is obsolete, please use mod_proxy or mod_fastcgi instead!
build-zope - Zope build script.
cron-zope - Demo script on how to connect to Zope from external program and call Zope objects/methods. Can pack Db.fs on a regular basis, e.g.
remote-backup - simple shell scripts that show how to use wget to do remote backup of a Zope object.
Also I wrote three demo toy Products to learn Product API.
