**** WARNING **** WARNING **** WARNING **** WARNING **** WARNING ****

Your version of DBD::SQLite currently installed ($DBD::SQLite::VERSION) uses
the old sqlite database format. This version of DBD::SQLite will *NOT*
open these files, and installing this module may cause problems on your
system. If this is a live environment you should upgrade with caution.

To upgrade a database, download and install both sqlite 2.x and 3.x from
http://www.sqlite.org/ and issue:

  sqlite OLD.DB .dump | sqlite3 NEW.DB

DBD::SQLite will NOT automatically upgrade a database for you, and using
this version against an old SQLite database WILL lead to database
corruption.
