[Zope] DTML Documents vs. Methods--Again? Yikes!

Greetings: I've been trying to figure out the difference between DTML Documents and DTML Methods. I'm reading the available docs, but true enlightenment still eludes me. :-) What are the tradeoffs in using these two seemingly similar objects? For example (and please feel free to expound on this), why is standard_html_header a DTML method and index_html is a DTML Document? Are there ZODB performance issues? Wishing there was Zope Zen pill available over the counter... -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.
