So the the controller is defined and used as the following?
<map:controller language="JavaScript">
<map:script src="prefs.js"/>
<map:script src="some-other-script.js"/>
</map:controller>
....
<map:match pattern="calc/*">
<map:flow function="calculator" continuation="{1}"/>
</map:match>
+1 on that. Seems to me the overall usage will be the same.
