[wp-testers] Enqueue script if shortcode exist

[John Blackbourn]

It can be done by placing wp_enqueue_script() inside your shortcode
function, but it requires more than Alex's example.

First, you have to set the 'in_footer' parameter of
wp_enqueue_script() to true, so the script is queued in the footer.
Then, you have to manually call wp_print_scripts() in the WordPress
footer so the script is output.

Scribu wrote a good tutorial on this subject actually:
