How to determine when my theme is deactivated?

Question

I'm using the following code branch to execute some theme setup options...

$myTheme_initialized = get_option('myTheme_initialized');
if (is_admin() && !$myTheme_initialized && isset($_GET['activated'] ) ) {
//do setup stuff
}

What hook can I tap into when the theme is deactivated?
