For help with relicensing efforts, I added this feature to MC1.5 (it
will be re-packaged as an addon in due course)

You can now inspect a package version for all contributors.

1) If you select a package "print authors" menu item is available in the
repository browser.
2) If no package is selected then "print all authors" menu item is
available, and it will scan through the entire list.
3) To scan an entire repository "switch to single column browser" first.
