Black magic... black magic.

Basically, YAML is the same thing as S-exprs or XML. It
represents a tree of nodes. Ruby mangles it into a tree of hash
maps (or whatever ruby calls them). It processes certain nodes
specially --- basically, it just evals them. Keys, for instance,
go something like this:

     CONFIG['control']['key'].each { |k, v|
        bind_key k *(eval "sub { |key| #{v} }")
     }

I'd personally probably stick with pure ruby, but the
config.yaml mangling is straightforward enough.
