Just an example of why we can't just put it in a file.  We have a number of
template libraries for our clients, such as an order page template library.
There are a limited number of configuration options that we want to store in
template variables, but we dont' want our clients to have to edit template
pages directly just for these few variables.  So I have a function that
stores the variables in a cache(memcache) backed by a database (values
frozen with Storable), and the header page thaws them out and sticks them
into a template hash.  Most clients don't get enough traffic where the
performance is an issue, and it if is then it's easy to just stick them
directly into the header file on a case by case basis.  For 95% of our
clients though it's much easier to just have a web page where they enter the
configuration variables and not have to worry about editing template pages
at all.
