| This class implements a JDBC driver wrapper which uses a custom
classloader to load a QED driver from a different (generally a previous
version) QED version. This setup permits multiple QED database versions
to coexist happily in the same JVM, to facilitate database migration
and other tasks where multiple versions must be accessed simultaneously.
The JDBC URL for this driver is of the form:
jdbc:mqed:database;qed=other-qed-jar [ ;other-props ]
In other words, it's a regular QED url, with the subprotocol changed
from qed to mqed, and with the additional
connection property qed=other-qed-jar.
