"include" directive for ipxe scripts?

[NiKiZe]

I'm assuming http server yes.
PHP is one method
havinging myscript.php

Code:

<?php header("Content-Type: text/plain"); ?>
#!ipxe
some scripting here .....
<?php include("other_file.ipxe"); ?>
more script

Note that this is just psuedo, is not tested, and should not be taken as an actual working example, just as example of the basic steps involved
