The late birth of the NEWS file also caused me to revisit the release

The late birth of the NEWS file also caused me to revisit the release
process once again and reconsider it in some detail.  In doing so,
some further revisions to the process were required:
1) The URL of the repository is embedded in the released code.
   - The packages need to be created from the tagged branch.
   - The URL then points to where to get the tagged code.
2) Improve the instructions for NEWS handling.
   - NEWS file must be updated for each release; describe that process.
   - The NEWS file should be archived an recreated for each release.
3) Add detail steps for the berliOS release process.
4) Minor cleanups to release process doxygen markup.
