Hi Stephen,

what's the reason, in details, of discouraging direct calls of
wp-config.php (or similar of wp-load.php)?
Sometimes I include wp-load.php in scripts external to WP, so I can
use e.g., database functions etc in those scripts.
Is that correct, or is to be discouraged, and if so, what is the
correct way to use WP environment in external scripts?

thanks in advance.
Claudio
