[Distutils] SetupTools: In Situ Upgrading

[Alexander Michael]

Once a script has started, is it possible to forcibly ignore the
version of a package listed in easy-install.pth and tell pkg_resources
to require a newer version that is available on the sys.path? The
script actually installs the newer version using easy_install, but now
I want the script to use the newer available version (and forget about
the older version).

Thanks for any hints,
Alex

By the way, it appears to me that in the EasyInstall documentation
(<http://peak.telecommunity.com/DevCenter/EasyInstall>) the option
--upgrade is elsewhere referred to as --update, but maybe it is my
misunderstanding.
