I was just catching up on some reading and after seeing some newbie
posts, I thought to mention this. A while ago I spent some time writing
a how-to on Zope and SQL integration for newbies. I found this part of
Zope (sticking zpt, script and zsql components together after
understanding what each did) to be quite difficult as a newbie.
Just in case it helps some people out there. All disclaimers given.
