+echo "SabreDAV migrate script for version 3.2\n";
+
+if ($argc < 2) {
+
+    echo <<<HELLO
+
+This script help you migrate from a 3.1 database to 3.2 and later
+
+Changes:
+* Created a new calendarinstances table to support calendar sharing.
+* Remove a lot of columns from calendars.
+
+Keep in mind that ALTER TABLE commands will be executed. If you have a large
+dataset this may mean that this process takes a while.
+
+Make a back-up first. This script has been tested, but the amount of
+potential variants are extremely high, so it's impossible to deal with every
+possible situation.
+
+In the worst case, you will lose all your data. This is not an overstatement.
+
+Lastly, if you are upgrading from an older version than 3.1, make sure you run
+the earlier migration script first. Migration scripts must be ran in order.
+
+Usage:
+
+php {$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
+
+HELLO;
