+                is conceptually similar to minisign.  Minisign creates signatures
+                that can be verified by signify, but signatures created by signify
+                <b>cannot</b> be verified by minisign because minisign expects
+                the trusted comment section to be present.  Trusted comments are
+                important to describe what has been signed in addition to the fact
+                that something has been signed.
