/**
 * 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.
