One of the most-frequently asked questions of all time is this: "I have a Python application I've developed; how do I deliver it to my customer/friend/...?"

Here are typical answers:

• tar up the source and send it. It's reasonable to expect that the end-user's host will have Python installed. MacOS comes that way; most Linux distributions do; and it's not onerous to insist that a Windows user install, for example, ActivePython;

• for Windows, use MovablePython;

• for this purpose, Pyrex can be regarded as a language variant to Python itself;

• Freeze

• cx Freeze

• py2app is for Macintosh

• py2exe

• PyInstaller (supports Windows, Linux and soon Mac)

• Python-Packager

• Esky (adds a bootstrap executable and allows to auto-update your applications over the network or from local directory; supports Windows, Linux and Mac)

FredrikLundh discussed some of these in 2003.

As of 2007, py2exe perhaps is second in use only to source distribution.
