 init.php written by Jeff Hoover
 - simplifies script initialization
 - puts HTML headers in an easy to call function

 ** NOTE that the following scripts do not use this file:
  - login.php
  - week_ssi.php
  - tools/send_reminders.php

 How to use:
 1. call include_once 'includes/init.php'; at the top of your script.
 2. call any other functions or includes not in this file that you need
 3. call the print_header function with proper arguments

 What gets called:

  include_once 'includes/config.php';
  include_once 'includes/php-dbi.php';
  include_once 'includes/functions.php';
  include_once "includes/$user_inc";
  include_once 'includes/validate.php';
  include_once 'includes/connect.php';
  load_global_settings ();
  load_user_preferences ();
  include_once 'includes/translate.php';
  include_once 'includes/styles.php';

 Also, for month.php, day.php, week.php, week_details.php:

  send_no_cache_header ();

//--------------------------------------------------------------------

// Get script name
$self = $_SERVER['PHP_SELF'];
if ( empty ( $self ) )
  $self = $PHP_SELF;
preg_match ( "/\/(\w+\.php)/", $self, $match);
$SCRIPT = $match[1];

// Several files need a no-cache header and some of the same code
$special = array('month.php', 'day.php', 'week.php', 'week_details.php');
$DMW = in_array($SCRIPT, $special);
