PyInstaller docker image fork used on build process

This is a temporary fork of docker-pyinstaller that uses zzhiyi's fork of wine to build with Python 3.7.1 and PyInstaller 3.4. Once those changes settles both in wine and docker-pyinstaller repo, this folder should be removed.

But hey, where is wine_3.20.1-1_i386.deb and how was it generated?

It's a package generated out of above mentioned wine branch. You can find instructions on how to generate Debian packages on the Wine Wiki or use a helper like docker-wine-builder.
