question?:                   should you permit the packing of multiple documents in single .xz ?

  open @opt.fns, parse file
    extract from file content:
      images and copy each image from whatever image source to _sisu/sisupod/sisu/_sisu/image

   remove previously existing contents of _/sisu/sisupod &
   make directory structure:

v3 -->
   _sisu
     sisupod
