User:Tholly/Rollback.js

//
//  **The script below is an adaption of one from [[w:User:Gracenotes/rollback.js]]**
//           **Please read that page for more details on the script.**
//
//  The Differences:
//  -Instead of just being able to:  $user --> username
//  -Now there is:  $user --> [[User:username|username]] - (linked)
//  -Also: $talk     --> [[User talk:username|talk]] - (linked)
//  -Also: $contribs --> [[Special:Contributions/username|contributions]] - (linked)
//  -Also: $ip       --> [[Special:Contributions/username|username]] - (linked). Used especially for IPs with no userpage.
//  -Also: $rvuser   --> [[User:User to revert to|user to revert to]] - (linked).
//  -Also: $rvip     --> [[Special:Contributions/user to revert to|user to revert to]] - (linked). Used for IPs with no userpage.
//
//  -Another change is that there is already text in the summary box, defaulting to: 
//   "Reverted edits by $ip ($talk) to last version by $rvuser."
//  -Finally, the link to click on next to rollback is "summary", not "sum"
//   and there are spaces between "rollback", "|" and "summary" to match other formatting.
//
