Unfortunately only a generic cygbuild sh script is supplied with the package - 
does nothing but complain without some other "magic" script or data! ;^>
Jari's Debian 8/9 xlsx2csv releases have been updated to 0.20+20161027 from 
0.11+20120814.

$ sed 1q xlsx2csv.py
#!/usr/bin/env python

Does not work with python3, nor after running 2to3 fixes - see attached logs - 
IANAPythonista

Anyway pylint was not useful compared to 2to3 - see attached pylint before and 
after 2to3 logs compared to 2to3 log.
