In your setup.py, add iconfile

This is a setup.py script generated by py2applet

Usage:
    python setup.py py2app

from setuptools import setup

APP = ['main.py']
DATA_FILES = []
OPTIONS = {
    'iconfile':'icon.icns',
    'plist': {'CFBundleShortVersionString':'0.1.0',}
}

setup(
    app=APP,
    name='MacApp',
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],

Answer 2

Answering my own question.

To add an icon file simply add the iconfile option when creating setup.py:

py2applet --make-setup foo.py --iconfile images/icon.icns

Note: You must not leave the icon.icns under the same folder as your main script foo.py. It must be placed under a subfolder like images/, otherwise you'd end up with DATA_FILE=['--iconfile'] in your setup.py, which would fail because that's not a data file.
