hi Gerry,

it exists in r2 (the module 'db') but doesn't currently in r2, though the
code would be quite similar. I suggest you download the r1 tarball and have
a look in user/mod/db.

That version of auth is a placeholder from R1. You're welcome to get it
functional if you'd like but it's far more simplistic than what we have
planned.

The table is created in the same way the database is, with a metabase schema
file.

That would be a single module, a master template isn't necessary for that to
work but would be nice if you'd like to have a banner/nav/etc.

A layout is a template.

Here's the deal:

    -Master templates are the top-level templates for the page types of a
site. For example, a master template might contain navigation, a logo, a
footer,  etc. and markers that tell pahe where to echo module group output.

    -A Layout template is used to 'layout' modules within a module group.
You probably won't use these that often, but when you need them you'll love
them. Say you have a module that echos a table, and another that echos some
text from a database field - now say you wanted to put... an image
in-between them on the page. But you don't want to add that image to either
module, and it would be stupid to create a module just to get an image tag
in-between these two modules: create a layout.

that make more sense? :)
