;;; This test suite looks for a configuration file named "test.config"
;;; This file contains a single a-list that specifies the connection
;;; specs for each database type to be tested. For example, to test all
;;; platforms, a sample "test.config" may look like:
;;;
;;; ((:mysql ("localhost" "a-mysql-db" "user1" "secret"))
;;;  (:aodbc ("my-dsn" "a-user" "pass"))
;;;  (:paostgresql ("localhost" "another-db" "user2" "dont-tell"))
;;;  (:postgresql-socket ("pg-server" "a-db-name" "user" "secret-password")))
