	// This php script will display a feedback page after any action of
	// adding/editing/deleting a record. It will display links to the
	// modified/added record as well as to the previous search results page (if any)
	// TODO: I18n


	// Incorporate some include files:
	include 'initialize/db.inc.php'; // 'db.inc.php' is included to hide username and password
	include 'includes/header.inc.php'; // include header
	include 'includes/footer.inc.php'; // include footer
	include 'includes/include.inc.php'; // include common functions
	include 'initialize/ini.inc.php'; // include common variables

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

	// START A SESSION:
	// call the 'start_session()' function (from 'include.inc.php') which will also read out available session variables:
	start_session(true);

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

	// Initialize preferred display language:
	// (note that 'locales.inc.php' has to be included *after* the call to the 'start_session()' function)
	include 'includes/locales.inc.php'; // include the locales

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

	// First of all, check if this script was called by something else than 'record.php' (via 'modify.php'):
	// Notes: - although 'receipt.php' gets actually called by 'modify.php', the referrer will be still set to 'record.php'
	//        - if a user clicks on Login/Logout while viewing a 'receipt.php' page she should get directed back to this receipt page (which is why 'receipt.php' must be also among the recognized referrers)
