Comment 2 for bug 127264

The new page, when viewed from an upstream (IProduct rather than IProductSeries as it is currently) context, should allow the user to specify the product series, the distribution release and the sourcepackage name.

When viewed from a sourcepackage (IDistributionSourcePackage) the user will be able to specify the distribution release and the product series to link to.

As a bonus, from the upstream context, if there is no tarball information provided for any series:
      Launchpad can automatically infer packaging links for you. All
      we need is a download directory URL for Firefox releases:
            [Firefox 1.0 |v] [http://releases.mozilla.org/firefox/1.0 ]
