Write a small DSL for converting a simple lisp expression to an MPD query
format. This turns, for example:
(and (= artist "Katatonia") (= album "Last Fair Deal Gone Down"))
Into:
((artist == "Katatonia") AND (album == "Last Fair Deal Gone Down"))
The expressions inside ‘query’ are quasi-quoted, so that variable substitution
is possible.
