the config.inc.php file will be created by the setup routine. It defines several important parameters which are needed by the moregroupware framework. All parameters are in a hashmap called $appconf. Below you can see an config.inc.php example:

<?php
      // this file is auto-generated by setup, only modify if you are sure what you do
      // Config File
      // Moregroupware.org
      // programmed by Marc Logemann
      // 01/04/01 (c)
      $appconf["dbvendor"] = "mysql";
      $appconf["dbhost"] = "localhost";
      $appconf["dbuser"] = "mgwuser";
      $appconf["dbpassword"] = "mgwpass";
      $appconf["dbname"] = "moregw";
      $appconf["rooturl"] = "http://localhost/moregroupware";
      $appconf["rootpath"] = "/home/apache/moregroupware";
      $appconf["theme"] = "default";
      $appconf["auth_method"]= "sql";
      $appconf["auth_ldaptype"]= "0";//0 for openldap; 1 for ADSI
      $appconf["auth_ldaphost"] = "";
      $appconf["auth_ldapbase"] = "";
      $appconf["auth_ldapuid"] = "";
      $appconf["auth_ldappasswd"] = "";
      $appconf["auth_ldapsuffixe"] = "";
      $appconf["create_accounts_on_login"] = 0;
      $appconf["mgw_version"] = "";
      $appconf["mgw_releasedate"] = "";
      $appconf["def_language"] = "de";
      $appconf["def_charset"] = "iso-8859-1";
      $appconf["html_compressor"] = false;
      $appconf["html_compressor_debug"] = false;
      define("SMARTY_DIR", "/home/apache/mgw/include/smarty/");
      define("ROOTPATH","/home/apache/mgw");
      define("INCLUDEPATH","/home/apache/mgw/include/");
      ?>
    

Its important to know that in each script, that starts with the necessary lines described above, you have access to the $appconf hashmap in order to use this settings, you will often need things like $appconf["rooturl"] or $appconf["rootpath"]. There are also 2 constant definitions, you will perhaps use ROOTPATH or INCLUDEPATH in order to include a different file.
