- * Replace Text - a MediaWiki extension that provides a special page to
- * allow administrators to do a global string find-and-replace on all the
- * content pages of a wiki.
- *
- * https://www.mediawiki.org/wiki/Extension:Replace_Text
- *
- * The special page created is 'Special:ReplaceText', and it provides
- * a form to do a global search-and-replace, with the changes to every
- * page showing up as a wiki edit, with the administrator who performed
- * the replacement as the user, and an edit summary that looks like
- * "Text replace: 'search string' * to 'replacement string'".
- *
- * If the replacement string is blank, or is already found in the wiki,
- * the page provides a warning prompt to the user before doing the
- * replacement, since it is not easily reversible.
