Downloading Popeye

Popeye executable

In order to use Popeye, you want to download an executable program or the source code to build an executable program yourself.

Windows: pywin64.exe
MacOS X: producing an executable for MacOS is always a hassle at best. I wasn't successful this time; if somebody can, I'll be happy to provide it here.
Linux:
   git clone https://github.com/thomas-maeder/popeye.git
   cd popeye
   git checkout v4.91
   ln -s makefile.unx makefile
   make
