Bare minimum to include in PHP file to use WP functions?
<p>I'm finding the documentation on coding WP stuff to be very lacking and can't figure out which files I need to include in my PHP script to get a bare minimum working code environment?</p>

<p>Example: I want to call <code>wp_insert_user()</code> to add a user to my site. How do I know which files in <code>wp-includes/</code> I need to include in my PHP script?</p>
