The function below could be a starting point of a more general
functionality: It takes a file and splits copys all headlines with a
certain level to a separate output file.

The more general functionality I am thinking of would be: Create
multiple output files for one or more input files that contain
headlines that match a certain criteria.

E.g.: Create output file "TODO.org" with all headlines with todo
keyword TODO or put all files with the tag "tag" into a output file
"tag.org" etc.

Things to consider:

  - escape sequences for output file names
    ("%number" -> counter, "%tag" -> tag etc.)

  - functions to move headline from here to there
    (copy, cut, cut and insert link)

  - maybe provide template for the output file's in file options
    (e.g. #+TITLE etc.)

For the splitting-by-level there is one caveat: The numbering of the
headlines is lost.

Definitively something that should be cooked up a little more.
