-This script help you migrate from a pre-1.7 database to 1.7 and later\n
-Both the 'calendarobjects' and 'calendars' tables will be upgraded.
-
-If you do not have this table, or don't use the default PDO CalDAV backend
-it's pointless to run this script.
-
-Keep in mind that some processing will be done on every single record of this
-table and in addition, ALTER TABLE commands will be executed.
-If you have a large calendarobjects table, this may mean that this process
-takes a while.
-
-Usage:
-
-php {$argv[0]} [pdo-dsn] [username] [password]
-
-For example:
-
-php {$argv[0]} "mysql:host=localhost;dbname=sabredav" root password
-php {$argv[0]} sqlite:data/sabredav.db

-  underscores).

-  any invalid lines.
-* Fixed: A bug in Windows timezone-id mappings for times created in Greenlands
-  timezone (sorry Greenlanders! I do care!).

-
