How to install Python Installer Package - PIP for Windows and Unix

"pip.py" is a Python package manager that automatically downloads and installs package updates and require libraries for Python packages much like the 'apt-get' utility does for Ubuntu.  The utility installs under your /<pythonDir>/tools/Scripts directory.  You will want to add this to your Path variable.  The ActiveState distribution of Python already comes with this package and their installer adds it to your path automatically.

You will need to install this package as it is not included with the Python.org distribution of Python.
