I'm trying to add support for SEPA on FacturaScripts, but with no doc from sephpa is not easy to understand what is every value and option and why I needed.

Fatal error: Uncaught exception 'AbcAeffchen\Sephpa\SephpaInputException' with message 'The values of iban, ci are invalid.

In this case, I know that IBAN is really invalid, I'm using some default values, but I don't know what is CI (Credito

I know the code is easy enough to write yourself. But it would be convenient if the export function would take an optional filename parameter to write to. And an optional keyword argument pretty=True to make the output human readable.

It would be great to add more examples of how this package could be used, e.g. in climate and hydrological research projects.
