within Python, one can either work in the root directory of the distribution
(where the subdirectory ``kwant`` is located), or make a (symbolic) link from
somewhere in the Python search path to the the package subdirectory.
The option ``--cython`` enables the translation of .pyx files into .c files.
It is only needed if any .pyx files have been modified.
