/**
* FrameInclude: Displays a url or page in a seperate frame inside our body.
*
* Usage:
* <?plugin FrameInclude src=http://www.internet-technology.de/fourwins_de.htm ?>
* <?plugin FrameInclude page=OtherPage ?>
* at the VERY BEGINNING in the content!
*
* Author: Reini Urban <rurban@x-ray.at>, rewrite by Jeff Dairiki <dairiki@dairiki.org>
*
* KNOWN ISSUES:
*
* This is a dirty hack into the whole system. To display the page as
* frameset we:
*
* 1. Discard any output buffered so far.
* 2. Recursively call displayPage with magic arguments to generate
* the frameset (or individual frame contents.)
* 3. Exit early. (So this plugin is usually a no-return.)
*
* In any cases we can now serve only specific templates with the new
* frame argument. The whole page is now ?frame=html (before it was
* named "top") For the Sidebar theme (or derived from it) we provide
* a left frame also, otherwise only top, content and bottom.

// $Log: FrameInclude.php,v $
// Revision 1.10 2004/06/14 11:31:39 rurban
// renamed global $Theme to $WikiTheme (gforge nameclash)
// inherit PageList default options from PageList
// default sortby=pagename
// use options in PageList_Selectable (limit, sortby, ...)
// added action revert, with button at action=diff
// added option regex to WikiAdminSearchReplace
//
// Revision 1.9 2004/02/17 12:11:36 rurban
// added missing 4th basepage arg at plugin->run() to almost all plugins. This caused no harm so far, because it was silently dropped on normal usage. However on plugin internal ->run invocations it failed. (InterWikiSearch, IncludeSiteMap, ...)
//
// Revision 1.8 2003/02/26 22:32:06 dairiki
// Wups. Delete disused cruft.
//
// Revision 1.7 2003/02/26 22:27:19 dairiki
// Fix and refactor FrameInclude plugin (more or less).
//
// (This should now generate valid HTML. Woohoo!)
//
// The output when using the Sidebar theme is ugly enough that it should
// be considered broken. (But the Sidebar theme appears pretty broken in
// general right now.)
//
// (Personal comment (not to be taken personally): I must say that I
// remain unconvinced of the usefulness of this plugin.)
//
// Revision 1.6 2003/01/18 21:41:01 carstenklapp
// Code cleanup:
// Reformatting & tabs to spaces;
// Added copyleft, getVersion, getDescription, rcs_id.
//
// For emacs users
// Local Variables:
// mode: php
// tab-width: 8
// c-basic-offset: 4
// c-hanging-comment-ender-p: nil
// indent-tabs-mode: nil
// End:
