What is Movable Python

Movable Python is a distribution of Python, for Windows,
that can run without being installed. It means you can carry a full
development environment round on a USB stick.

It is also useful for testing programs with a 'clean Python install',
and testing programs with multiple versions of Python.

The GUI program launcher makes it a useful programmers tool, including
features like :

• 
  
• Log the output of all Python scripts run
  
• Enable Psyco for all scripts
  
• Quick Launch buttons for commonly used programs
  
• Configure multiple interpreters for use from a single interface
  

It comes with the Pythonwin IDE and works fine with other IDEs like
SPE

http://developer.berlios.de/projects/python/.

Plus many other features and bundled libraries.""")
