AutoWikiBrowser
AutoWikiBrowser (AWB) is a semi-automated MediaWiki editor designed to make tedious or repetitive editing tasks quicker and easier. It is a .NET desktop application which includes a browser that follows a user-generated list of pages to modify, presenting changes to implement within each of those pages, then progressing to the next page in the list once the changes are confirmed or skipped by the user. When set to do so, it suggests some changes (typically formatting) that are generally meant to be incidental to the main change.
