;;;====================================================================
;;; Generic functions for querying the database
;;;
;;; FIXME: how sane is this? The idea was to have a general mtp-admin.
;;;
;;; What about arbitrary SQL conditions? Might be useful for general
;;; searching, and defining new datasets (which I currently do by
;;; writing the resuls of a SQL query to a file (e.g. `all the Beatles
;;; songs'), and then reading the file into lisp). Amuse-midi-db
;;; implements these methods.
;;;
;;; Also, should this kind of generality be extended to data import
;;; and export?
