-    * Display the admin/language menu and process strings translation.
-    *
-    * CHANGES
-    *
-    * 2006/06/08 mudrd8mz
-    * 1) Fixed bug 5745 reported by Harry Smith so now can edit en_utf8_local pack
-    * 2) More notification messages included
-    *
-    * 2006/05/30 mudrd8mz
-    * Merged with version by Mitsuhiro Yoshida - display icon links instead of text links
-    * (I have changed the position of arrow icons to not to be so close each other)
-    *
-    * 2006/05/19 mudrd8mz
-    * A lot of changes to support translation of *_utf8_local langugage packs. Needs testing
-    *
-    * 2006/05/16 mudrd8mz
-    * 1) LANG_DEFAULT_FILE can be now set. moodle.php used to be opened automatically.
-    *    As it was (and still is) one of the biggest files it usually took a long time to load the page
-    *    even if you just want to choose the file to translate.
-    * 2) added links from "missing" to "compare" mode page
-    * 3) english strings are now key-sorted in "missing" mode
-    * 4) list of files with missing strings is now displayed at the top of "missing" page
-    *
-    * 2006/05/14 mudrd8mz Improvements of lang.php,v 1.65 2006/04/10 22:15:57 stronk7 Exp 
-    *  1) "go to first missing string" link can be displayed (see LANG_DISPLAY_MISSING_LINKS)
-    *  2) "go to next missing" link can be displayed (see LANG_DISPLAY_MISSING_LINKS)
-    *  3) submit button may be repeated (see LANG_SUBMIT_REPEAT*)
-    *  4) added (empty) "summary" attribute for the <table>'s
-    *  5) added error_reporting(E_ALL ^ E_NOTICE); in "compare" mode (even in debug environment
-    *     we know that missing keys are missing strings here, not bugs ;-)

-XMLDB - Base classes and edition interface.

-Complete Documentation:

-Ciao, Eloy Lafuente (stronk7)
-
-========== ========== ========== ========== ==========
-========== ==========   HISTORY  ========== ==========
-========== ========== ========== ========== ==========
-
-2006-08-07 - Editor working on production
-
-The editor has been used succesfully to build
-a bunch of install.xml files and everything
-seems to be working properly.
-
-========== ========== ========== ========== ==========
-
-2006-07-11 - PHP4 compatible release
-
-Now everything seems to be working under PHP 4. What
-a horrible OOP implementation!
-
-Note that write permissions to */db dirs are required.
-
-Now working in the 3 missing forms, to manually edit
-fields, keys and indexes.
-
-Ciao, Eloy Lafuente (stronk7)
-
-========== ========== ========== ========== ==========
-
-2006-07-11 - Important notes
-
-I've just discovered this some seconds ago, in order
-to test properly the XMLDB classes and editor:
-
-1.- PHP 5 required for now. Will change this soon.
-2.- Perms to "apache" user needed in */db
-    dirs in order to allow the XMDBD interface
-    to write files.
-
-Ciao, Eloy Lafuente (stronk7)
-
-========== ========== ========== ========== ==========
-
-2006-07-11 - Initial commit
-
-This directory contains the XMLDB classes to be used
-under Moodle > 1.7 to store all the DB info in a
-neutral form (classes dir). Also it contains one simple
-interface to edit all those structures.
-
-To install and test it, simply copy the whole xmldb directory
-under your moodle/admin dir and point your browser (as admin)
-to http://your.server/moodle/admin/xmldb
-
-The edition interface isn't completed yet (it laks 3 more forms
-to edit fields, keys and indexes) and there isn't any lang file
-(although I hope everything is really clear).
-
-The edition interface includes one reverse-engineering tool that
-provides an easy way to retroffit and to generate any table from
-MySQL to the new XMLDB format.
-
-Once the XMLDB format was approved, we'll be able to build all the
-"generators" needed in order to use it to create Moodle DB structures
-for each RDBMS flavour.
-
-Once the interface was finished (2-3 days from now) related documentation
-will be sent to http://docs.moodle.org/en/XML_database_schema in order
-to comment/modify/approve the final XML format.
-
-All the code is, obviously GPL, with its copyrights and so on...
-
-Ciao, Eloy Lafuente (stronk7) :-)
