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