Twinkle is a JavaScript application that gives Miraheze Editors a quick way of performing common maintenance tasks, such as nominating pages for deletion and cleaning up vandalism.
See Wikipedia:Twinkle on the English Wikipedia for more information.
AzaToth is the original author and maintainer of the tool, as well as the morebits.js library gadget, which forms the basis for many Wikipedia scripts and editing tools in addition to Twinkle.
