   Warning: Package 'karax' has an incorrect structure. It should contain a single directory hierarchy for source files, named 'karax', but file 'ajax.nim' is in a directory named 'examples/ajax' instead. This will be an error in the future.
      Hint: If 'examples/ajax' contains source files for building 'karax', rename it to 'karax'. Otherwise, prevent its installation by adding `skipDirs = @["examples/ajax"]` to the .nimble file.
