title: How to install PyPy in anaconda
body: <p>I have a Linux-64 bit machine. How do I install PyPy in my anaconda environment. I tried conda install pypy. It says there are no available packages. pip install pypy also returns a similar message. Is it that the only way to install PyPy is by downloading the tar.gz file from the website? Once installed, how do I configure my Anaconda environment in such a way so as to be able to switch from PyPy to other Python implementations when required?</p>
