To paraphrase:

.yaws file: sprinkle a little Erlang into your HTML
appmod: sprinkle a little HTML/XML/JSON/whatever into your Erlang

An appmod is like a servlet, I suppose. It's code that handles
requests made to a configured portion of the server URI space (the
path can be "/" to handle all requests to that server), and can do
pretty much anything it needs to in order to fulfill each request.

In my own development work with yaws, I use appmods almost exclusively
because they're totally flexible.
