// IMPORTANT NOTE: Use of the ***configurator.php*** to generate an
// index.php is depreciated, because it is out of date and a new
// configuration system is in the works (see the config directory, not
// finished yet though). DO compare or diff the configurator's output
// against this file if you feel you must use it to generate an
// index.php!

//   * don't store cookie prefs with sessions
// stdlib: global obj2hash helper from _AuthInfo, also needed for PagePerm

//
// Revision 1.119  2004/02/01 09:14:10  rurban
// Started with Group_Ldap (not yet ready)
// added new _AuthInfo plugin to help in auth problems (warning: may display passwords)

// renamed LDAP_AUTH_SEARCH to LDAP_BASE_DN
// changed PHPWIKI_VERSION from 1.3.8a to 1.3.8pre
// USE_DB_SESSION defaults to true on SQL

//
// fixed the IndexAsConfigProblem logic. this was flawed:
//   scripts which are the same virtual path defined their own lib/main call
//   (hmm, have to test this better, phpwiki.sf.net/demo works again)
//
// Revision 1.118  2004/01/28 14:34:13  rurban
// session table takes the common prefix
// + various minor stuff
// reallow password changing
//
// Revision 1.117  2004/01/27 23:25:50  rurban
// added new tables to mysql schema
// fixed default DBAUthParam samples to match these
// added group constants (look terrible, I'd prefer strings instead of constants)
//
// Revision 1.116  2004/01/25 04:21:02  rurban
// WikiUserNew support (temp. ENABLE_USER_NEW constant)
//
// Revision 1.115  2003/12/22 04:58:11  carstenklapp
// Incremented release version.
//
// Revision 1.114  2003/12/05 16:00:42  carstenklapp
// ACK! gettext is not available at this point in index.php.
//
// Revision 1.113  2003/12/05 15:51:37  carstenklapp
// Added note that use of the configurator is depreciated.
//
// Enable localization/gettextification of $KeywordLinkRegexp. (Also, now
// users not familiar with regex can more easily just edit the $keywords
// array).
//
// Added four new constants to define author and copyright link rel~s
// used in html head. This makes it easier to run multiple wikis off of
// one set of code.
//
// Eliminated RECENT_CHANGES constant for RSS auto discovery because it's
// another step to watch out for when running a non-english wiki. Now
// simply defined as _("RecentChanges") in head.tmpl itself. Non-standard
// wikis where the RecentChanges page has been named to something else
// will have to modify this in head.tmpl (along with all other places the
// word RecentChanges appears in the code, something that already would
// have had to be done on such a wiki anyway).
//
// Added a little more info and instructions to flesh out:
// DEBUG, WIKI_NAME, ADMIN_USER, $DisabledActions, $DBParams, CHARSET.
//
// A few typos and spelling mistakes corrected, and some text rewrapped.
//
// Revision 1.112  2003/11/17 15:49:21  carstenklapp
// Updated version number to 1.3.7pre (beyond current release
// 1.3.6). Disabled DEBUG output by default (hide DebugInfo, XHTML &
// CSS validator buttons). Note the DebugInfo button remains visible
// for the Admin, and can be accessed by anyone else by adding
// "?action=DebugInfo" to the URL for the occasional use.
//
// Revision 1.111  2003/03/18 21:40:04  dairiki
// Copy Lawrence's memo on USE_PATH_INFO/AcceptPathInfo to configurator.php
// (as promised).
//
// Plus slight clarification of default (auto-detect) behavior.
//
// Revision 1.110  2003/03/18 20:51:10  lakka
// Revised comments on use of USE_PATH_INFO with Apache 2
//
// Revision 1.109  2003/03/17 21:24:50  dairiki
// Fix security bugs in the RawHtml plugin.
//
// Change the default configuration to allow use of plugin, since

// work on locked pages.)

//
// Revision 1.102  2003/02/22 18:53:38  dairiki
// Renamed method Request::compress_output to Request::buffer_output.
//
// Added config option to disable compression.
//
// Revision 1.101  2003/02/21 19:29:30  dairiki

//
