-------------------------+---------------------
 Since I want to live without Python 2.7 from MacPorts (the macOS one
 should suffice) I started to change libzzip – which only needs Python 2 to
 create the documentation. By using Python's 2to3 some Python files were
 adapted to Python 3 – and the documentation built! It's also usable.

 Could be the translation is not perfect, because when building the
 documentation around 10,000 lines à la

 {{{
 Unescaped left brace in regex is passed through in regex; marked by <--
 HERE in m/<([^<>]*)\${ <-- HERE src_dir:[?]([^{<>}]*)}([^<>]*)>/ at (eval
 325) line 292, <STYLESHEET> line 19691.
 }}}

 are emitted (this is certainly from Perl). So next TeX Live release could
 be a bit more up-to-date.

 The attached patch files either translate the needed Python files or
 correct a minor fault in one Makefile.
