/*
* This file implements two hostrealm modules named "test1" and "test2".
*
* The first module returns multi-element lists. For host_realm and
* fallback_realm, it returns a list of the host's components in order. For
* default_realm, it returns a list containing "one" and "two".
*
* The second module tests error handling. For host_realm and fallback_realm,
* it returns a fatal error on hosts beginning with 'z', a list containing "a"
* for hosts beginning with 'a', and passes control to later modules otherwise.
* For default_realm, it returns a fatal error.
