/* This, as you have probably guessed, is the crux on which SMF functions.
Everything should start here, so all the setup and security is done
properly. The most interesting part of this file is the action array in
the smf_main() function. It is formatted as so:
'action-in-url' => array('Source-File.php', 'FunctionToCall'),
Then, you can access the FunctionToCall() function from Source-File.php
with the URL index.php?action=action-in-url. Relatively simple, no?
