Upgrading Pastebin
------------------

v0.4x to 0.5
------------

The database has some extra columns, add and initialise them as follows:

ALTER TABLE pastebin 
	ADD COLUMN expires DATETIME,
	ADD COLUMN expiry_flag ENUM('d','m', 'f') NOT NULL DEFAULT 'm';
	
UPDATE pastebin SET expires=DATE_ADD(posted, INTERVAL 1 MONTH) where expires is null and expiry_flag='m';
