/**
* From [[w:User:Gracenotes/rollback.js]].
* This script lets you use a custom summary with the rollback feature
* by adding a "sum" link wherever a rollback link appears. When you
* click "sum" you are prompted for a custom summary, and the script
* adds an additional summary parameter to the rollback URL submitting it.
*
* For usage and extra options, see the talk page.
