+Symlink this file to root  __main__.py

+This file is an alternativ to the python launcher ./$(PROGRAM) when using zipapp.
+Any code changes there must be manually recplicated here.
+
+We do NOT need to change the working dir here, as in the direct launcher.
+python zipapp uses indeed zip and will resolve symlinks to real files, thus this will become
+a real file in the right place, resulting in the right cwd.
