#34 (comment):

We've been pointing http://ramdajs.com/docs/ at the current build's API docs. I thought that had been automated by the build, but it didn't happen here.

I had thought that this target would match docs/index.html:

%: $(VERSION)/%
    cp '$<' '$@'

Apparently % does not perform matches across path components, so the target above matches style.css but not docs/index.html.
