27.3. py2app

py2app (http://undefined.org/python/py2app.html) is a distutils extension that builds standalone Python applications for the Mac. py2app is distributed with PyObjC (http://pyobjc.sourceforge.net/), the Python/Objective C bridge that offers an excellent way to create Mac applications with Cocoa interfaces in Python; however, py2app is also fully compatible with all major cross-platform GUI toolkits for Python, including Tkinter, wxPython, pygame, and PyQt. Moreover, py2app lets you build installer packages (.mpkg files) directly. Refer to the URL for all practical usage details.
