+# Can use this script to create the tag for a main-intel rebase. This
+# should technically work for any branch but it has NOT been tested with
+# other than main-intel.
+#
+# If you want to reuse an existing repo, this script makes an attempt to
+# clean up. It will nuke, or should, ANYTHING that hasn't been pushed to
+# remote. It deletes existing local tags and fetches them fresh. Don't be
+# alarmed at the "Deleting tag spew at the command line. It is not nuking
+# remote tags.
+#
+# Generates the tag and then shows the details, then prompts for the push
+# at the end.
