+# %p    The empty string when no passphrase is needed,
+#       the string "PGPPASSFD=0" if one is needed.
+#
+# %f    Most PGP commands operate on a single file or a file
+#       containing a message.  %f expands to this file's name.
+#
+# %s    When verifying signatures, there is another temporary file
+#       containing the detached signature.  %s expands to this
+#       file's name.
+#
+# %a    In "signing" contexts, this expands to the value of the
+#       configuration variable $pgp_sign_as.  You probably need to
+#       use this within a conditional % sequence.
+#
+# %r    In many contexts, mutt passes key IDs to pgp.  %r expands to
+#       a list of key IDs.
+
+# Note that we explicitly set the comment armor header since GnuPG,
+# when used in some localiaztion environments, generates 8bit data
+# in that header, thereby breaking PGP/MIME.
