A silly question, really, but still

Where do I put the module referenced by start_mod for it to be called by yaws?

For instance,

<server umc>

        start_mod = umc  # where should umc.erl go?

        port = 81
        listen = 0.0.0.0
        docroot = /Users/dmitriid/Projects/www/umc/www/
        appmods = </, erlyweb>
        <opaque>
                appname = umc
        </opaque>
</server>
