By default it uses PHP's sys_get_temp_dir() to get writeable directory and  
if that fails, falls back to standard temp paths (supports Windows).
User doesn't have to configure anything. It should just work on any sane  
setup. The option is there only for insane setups ;)

Currently it's not possible to store compiled templates in the DB. I  
applaud your intention of making easily installable application, but I'm  
not convinced that DB storage is needed and worth the effort. Among other  
things it would involve use of eval() which makes it impossible for PHP  
accelerators like APC to cache templates.

You can catch (IMHO very rare) case when server doesn't have writeable  
temp dir:

if (!is_dir($phptal->getPhpCodeDestination()) ||  
!is_writeable($phptal->getPhpCodeDestination()))
{
// display setup instructions and/or change configuration with  
$phptal->setPhpCodeDestination()
}
