<?php
/**
 * @file
 * gmap.strings.php
 * PURPOSE
 *
 * This is a stand-alone script which
 * takes markers titles and wraps them in t()'s.
 * The reason we want to do this is because variables
 * can not be passed through t() with .pot files generated
 * by the potx module.
 *
 * The result of running this script should be the creation
 * of a file in the root of the gmap module's directory, called
 * 'gmap.strings.inc', containing a function 'gmap_marker_labels'
 * which returns an array holding each of the  marker labels wrapped in t().
 *
 * INSTALLATION
 *
 * This script needs to be run within drupal, so the best way
 * to accomplish this is to install and enable the devel module, then,
 * enable the 'Execute PHP' block somewhere.
 *
 * Then, just paste this script into the text field in the Execute PHP block,
 * and click 'Execute'!
 * This will create the gmap.strings.inc file in the gmap module's directory -
 * be sure to adjust the permissions of this new file appropriately!
