I have looked at the Wiki and quite a few posts, but I have a feeling the way to make this work has changed a bit (since some of this information has been posted). So sorry for the dumb question, but just no luck finding this ...
I have a package that is working well on my router itself (i.e. files modified, Lua and JS / HTML work fine). I tried to add them inside LuCI packages on the source side, but no joy getting the package to show up in menuconfig (even with a full clean) or in the build.
