+This demo shows how a Firebird database can be used for VisualPlanIt. It 
+takes advantage of the prebuilt TVpFirefordDatastore.
+
+NOTE:
+The project creates a new database on the fly. For reasons unknown at the moment,
+an exception is raised here if started from the IDE. This does not happen any
+more once the database exists.
