The release.sh (based heavily on generate-release.sh) has been
used for the 9.2-RELEASE and 10.0-RELEASE cycles, so make sure
there is no confusion on what is currently being used by having
two similar scripts.
A big "thank you" to Nathan Whitehorn, the author of the
generate-release.sh script, for writing this utility.
No objection: nwhitehorn
