compile all templates at once

Hi,

1) is there a way to tell Smarty to compile all templates
from smarty/templates to smarty/compile without clicking
through all www pages and waiting till all templates have
been visited and compiled?

2) Since templates are compiled they can be encoded with
Zend and posted to clients server. Is there any Smarty setting that
should be reset to zero to avoid template recompilation after some
X days? In other words - how to make sure that templates
are not being tried to recompile after some period of time?

Thanks,
Maris
