Command to generate SSH key on Linux

Because ssh-keygen has human unfriendly command line interface without --help option, here is a quick reminder how to generate very secure SSH key valid for one year (52 weeks) with "13.04" comment for its public part:

ssh-keygen -t rsa -b 4096 -V +52w -C 13.04

This key can be used to avoid typing password when pushing your Python code to sites like Bitbucket or GitHub (Google Code is not there yet) or to securely upload your packages to PyPI.
