/**
* Extension CreateArticle.php
*
* @author Lisa Ridley <lhridley@theridleys.org>
* @copyright Lisa Ridley
* @license GNU
* @version 0.91beta 20 Mar 2007
*
* This extension is a derivation of the <inputbox> extension by Erik Möller
*
* To implement this extension, save in the extensions/ folder as CreateArticle.php
* and insert the following line into LocalSettings.php, near the end:
*
* require_once("$IP/extensions/CreateArticle.php");
*
* or if that doesn't work try:
*
* require_once("extensions/CreateArticle.php" );
*
* This extension has been tested and verified to work with version 1.6.9
*
* Instructions: To use this extension, insert the following tag into a
* MediaWiki article page:
* <createarticle>
* type=createarticle
* argument=
* ....
* </createarticle>
*
* The following are valid arguments:
* type=createarticle (this is the only valid argument, but future functionality is
* under development
* prefix=a prefix for page creation. This will be added to the beginning of
* the article name created. Good for assigning articles to namespaces.
* subpage=a suffix for page creation. This will be added to the end of the
* article name created. For valid subpages, make sure you use a "/" at
* the beginning of the subpage name (ex: /article)
* width=the width of the text creation input field (defaults to 50)
* preload=the name of the template in the MediaWiki namespace that holds the
* text you wish to preload in the newly created article page
* editintro=the name of the template in the MediaWiki namespace that holds the
* instructions you wish to have displayed above the article creation input
* box
* default=the default text you want to show in the article creation input box
* bgcolor=color you want the background display to be
* buttonlabel=text you want to show in the create article button. Defaults to
* label stored in MediaWiki:createarticle system message which is
* "create article" unless it has been overridden
* align=position of create article box on the page; valid arguments are left,
* center, and right; defaults to center
*
* Note: While this feature will work with subpages, there is no check to see
* if creating a subpage is a valid act (i.e. $wgNamespacesWithSubpage is not
* checked)
*
