 331  * Contributions which are marked "top" are currently on top of the history.
 332  * For these contributions, a [rollback] link is shown for users with sysop
 333  * privileges. The rollback link restores the most recent version that was not
 334  * written by the target user.
 335  *
 336  * If the contributions page is called with the parameter &bot=1, all rollback
 337  * links also get that parameter. It causes the edit itself and the rollback
 338  * to be marked as "bot" edits. Bot edits are hidden by default from recent
 339  * changes, so this allows sysops to combat a busy vandal without bothering
 340  * other users.
 341  *
 342  * @todo This would probably look a lot nicer in a table.
