+Setting XML files are now stored in etc/settings instead of etc. This
+reflects the layout with the Debian package layout.
+
+Settings may be posted for command=settings. The POSTed settings must
+have root element 'settings' like regular setting files. In order to be
+recognized, the POST request must use Content-Type=text/xml.
+
+A service may be posted for command=init. This service will be used
+during the session. The service may have its own target settings,
+ICU config, timeout, etc. In order to be recognized, the POST request
+must use Content-Type=text/xml.
+
+Timeout values may be given per-service. That's element 'timeout'
+which takes three attribute values (a subset may be given): 'session',
+'z3950_connect', 'z3950_session'. Option -T is no longer supported
+- used to specify session timeout.
+
Option -t tests the Pazpar2 configuration and returns exit code
(0=success, non-zero=failure). In previous version of Pazpar2, -t
specified local settings.
