Install and use pip in a local directory without root/sudo access.

Install and use pip in a local directory without root/sudo access.

Why?

Many users when are given server access, do not have root (or sudo) privileges and can not simply do sudo apt-get install python-pip . Here's an easy way you can install and use pip without root (or sudo) access in a local directory. Note : This works without easy_install too.

How?
