 Usage: $0 <secret> <manifest>
+
+sign.sh adds lines to a manifest to indicate the approval
+of the integrity of the firmware as required for automated
+updates. The first argument <secret> references a file harboring
+the private key of a public-private key pair of a developer
+that referenced by its public key in the site configuration.
+The script may be performed multiple times to the same document
+to indicate an approval by multiple developers.
