Seed #release-archival.

Use content from the FAQ "How Is An Old Release Moved To The Archives?".
Replace passive archival description with command.

Archival to archive.apache.org may happen automatically as a side
effect of uploading to the canonical release channel, but that
implementation detail doesn't impact policy.
Require full text of ALv2 in LICENSE.
Link to NOTICE spec rather than spell things out.

Specifying the contents of NOTICE in exhaustive detail with multiple
redundant examples (as is done elsewhere on the releases page) is not
appropriate for a policy document when a canonical policy exists
elsewhere.  Therefore, refer only to Apache licensing policy, with an
additional link to the ALv2 itself.
Copy FAQ entry about multiple licenses.
Codify rules for multi-licensed packages.

*   Change "should" to "MUST" in several places to reflect my
    understanding of policy.
*   Use the more specific term "bundles" instead of "contains".
Copy "where do releases go" FAQ to "Distribution".
Clarify canonical distribution requirement.

Add explicit language requiring that official releases be uploaded to
the canonical distribution channel.

Eliminate incorrect language suggesting that a release is not "released"
unless it is uploaded.  If, say, a release vote passes and then the
artifacts are made available to the general public through alternate
channels, the release remains an "act of the foundation".
Generalize redistribution.

Allow redistribution not only through Maven and repository.apache.org
but through any other channel, subject to licensing constraints.
Remove redundant sentence from Distribution.

The requirement that source be sufficient to build any supplied binaries
is covered in the section "Compiled Packages".
Reword PMC distro dir responsibilities.

Use imperative commands rather than observational style.
Seed Licensing Documentation.

Use content copied from #distribute-other-artifacts.
Remove redundant materials.

Signature requirements within the distro dir are covered under "Release
Distribution".  The other sentence repeats material in the preceding
paragraph.
Formalize LICENSE/NOTICE file requirements.

Require that each package provide them and specify their locations.
Require minimal LICENSE/NOTICE.

Specify that LICENSE/NOTICE must reflect the package's exact content.
Clean up Licensing requirements.

*   Upcase imperatives.
*   Include a general reference to Apache Licensing Policy, rather than
    link to a limited selection of licensing categories.
