I've been working with .91-bugfixes for a long time, and moving into
the development version makes me feel like a stranger lost in a
wonderful, yet foreign, country. I have no doubt all the changes are
for the better, but I'm a little tripped up on managers. (probably
because I never fully grasped _module methods)

DjangoBook gives me a few examples in Chapter 15, but refer to chapter
5, which doesn't have anything about managers in it.

>From the docs:

I'm not sure what this means. Can anyone explain what is meant by
"table-level" functionality or provide a simple  example? (and again
for row-level?)

If I understand correctly, it seems that a manager could more cleanly
accomplish a lot of my recordset lookups that use a lot of arguments?
