      Tools from the vengi C++ voxel game engine. It includes a voxel editor
      with character animation support and loading/saving into a lot of voxel
      volume formats. There are other tools like e.g. a thumbnailer for your
      filemanager and a command line tool to convert between several voxel
      formats.
