If the versions are not equal and the version.devel property is false, the user will be presented an error message when syncing.
Developers can set the version.devel=true to subvert the check.
A new database script, create.rtversion.sql will need to be updated and run for each release.
Users will see appropriate message if the the client version is newer, older, or if there is no rtversion table in the database.
