[Distutils] upgrade functionality

[Flavio Codeco Coelho]

Hello,

Does setuptools have any mechanism for upgrading all packages installed
with easy_install? Something similar to an "apt-get upgrade"?

I have dozens of packages that have been installed with easy_install, to
the point that I can't even recall the whole list. I worry that they are
getting outdated...

Naturally, the packages I Use more often get upgrade as I see fit but
the others...

Thanks,

Flávio
