Converting vbcodes

If I write a new script, how do I get anything submitted to it to be parsed through the vbcode convertor.
Is there some way I can call a function in another php file?

Also, which file converts vbcodes?

(so I could just copy the code over from that file into my script)

The function bbcodeparse2() does the parsing, and it's in functions.php. You will need to start a MySQL connection though, since that function grabs your custom vB Codes and smilies from the database.
