Upgrading all packages with Pip

Question

Is it possible to upgrade all python packages at one time with Pip?

I saw someone made this a issue: http://bitbucket.org/ianb/pip/issue/4/add-upgrade-and-upgrade-all-commands

There isn't a built-in flag yet, but you can use

pip freeze | cut -d = -f 1  | xargs echo pip install -U
