I am struggling with setting up a yapp for Yaws. I am seeking either a link to the right documentation, or a short example.
Assuming you have checked the Yaws yapp page (be sure to "make docs" in yaws/applications/yapp directory of the checked out files) the author of yawn has posted a couple of good "make it work" wiki entries.
Also poke around on the yaws mailing list, there are a few regulars that jump in on yapp questions there
