* fix #13150 `nim doc --project` works with duplicate names and with imports below main project file * add to help; fixup after #13212 isRelativeTo got merged * fix test tests/compilerapi/tcompilerapi.nim * remove nimblePkg field; compute on the fly instead * kochdocs: compiler docs now under compiler/ * --docRoot now has smart default: best among @pkg, @path
