Please clarify what this script is, and how you want it 'available'. Is it a standalone page or shell script, or is it code to be stuck inside some part of SMF (additional function on the page)? How are you thinking of invoking it -- as part of SMF or something completely on its own? If it's standalone, just give it a nonguessable name and stick it in your site root. If it's meant to interact with SMF in some way, or be embedded in it, we'll need to know a lot more about it.
