Script autoloading

Hi all,
I have written a script that scans my gameScripts directory and executes each one...

function loadScripts(%pattern) {
	echo("begin load...");
	%filename = findFirstFile( %pattern);
	while("" !$= %filename) {
		echo("loading..." SPC %filename);
		exec(%filename);
		%filename = findNextFile( %pattern );
				
	}
}

	loadScripts("~/gamescripts/*.cs");

This works great until I package my game which deletes the *.cs files. The "findFirstFile" function then finds nothing and executes no scripts. I have spotted the findFirstFileMultiExpr which "Finds a file on the file system matching one of several patterns." However, how do I pass multiple patterns to this function? I've tried spaces, commas, semicolons, etc.
