Authorship and copyright of derived exporters

[Robert Klein <roklein@roklein.de>]

Hi,

I've been wondering, whom to put on the copyright line and author: lines
in a derived exporter.

For example, I have an exporter derived from the LaTeX backend which
basically is:

- the (org-export-define-derived-backend ...) call
- a renamed copy of org-latex-template modified by adding
  - five lines of comment
  - five times three lines of code
- a copy of the end-user functions of the LaTeX exporter,
  - the functions renamed for the derived exporter
  - 'latex inside them replaced for the derived exporter
- a couple of comment lines explaining the derived exporter



On the other side, I have another derived exporter (from the HTML
backend, this time) with way more of I've written myself,  but still the
end-user functions of the html backend (-export-as-html,
-convert-regino-to-html, -export-to-html, and -publish-to-html) copied,
renamed and 'html replaced inside those functions.


Should I copy the authors of the backends I derived from into my
file(s)?  I'd rather not leave them out, but, on the other hand, maybe
they don't want to be associated with my sometimes paltry attempts at
coding.

Thank you very much for your advice.

Best regards
Robert
