Actually I conclude that the current wman apps for werc sucks big time. All I really want is, that if there is a *.[1-9] file in the directory, it will be formatted using troff instead markdown. That's much simpler and the man pages would appear in the site menu.
I will hack this and get rid of wman. Having said this, I think I simplified and changed werc quite a bit, so that I will suggest to use our werc as official werc2 to Uriel ;) Cheers, Anselm
