What is the best way to make wording changes (e.g. 'Edit this page' to 'Edit current page')? I know I could edit the string:
$lang['btn_edit'] = 'Edit this page';
in the file:
inc/lang/en/lang.php
But that has the disadvantage of getting overwritten next time I upgrade. Is there a local language configuration file, akin to the local.php config file, that I can use to override a few specific strings from inc/lang/en/lang.php?
