Comment 5 for bug 407458

Just added a commented blob-storage def in grokproject paster template.

What's still missing are hints for blobs-and-ZEO configurations, but this might also give an overload of example configs. Maybe we should setup a page describing all the ZODB options somwhere on grok.zope.org? Or is there already such a page? I currently dig component.xml in ZODB repository to lookup all that stuff.
