BlogProfile - Funky PHP

[Gazley]

Hi there,

Looking at the BlogProfile and noticed the following:

if(count($page->categories)) $subnav .= renderNav(__('Related Categories'), $page->categories);

renderNav is a function and the first argument (above) starts with two underscores __ followed by ('Related Categories')

What kind of value is that? I haven't seen that before and would appreciate an explanation. Is it some kind of PHP 'magic' thingy?

Thanks.

It's multi language domain translation function. Makes text in templates and modules and admin translateable.
