+@defvar gnutls-verify-error
+The @code{gnutls-verify-error} variable allows you to verify SSL/TLS
+server certificates for all connections or by host name.  It defaults
+to @code{nil} for now but will likely be changed to @code{t} later,
+meaning that all certificates will be verified.
+
+There are two checks available currently, that the certificate has
+been issued by a trusted authority as defined by
+@code{gnutls-trustfiles}, and that the hostname matches the
+certificate.  @code{t} enables both checks, but you can enable them
+individually as well with @code{:trustfiles} and @code{:hostname}
+instead.
+
+Because of the low-level interactions with the GnuTLS library, there
+is no way currently to ask if a certificate can be accepted.  You have
+to look in the @code{*Messages*} buffer.

 @defvar gnutls-min-prime-bits
 The @code{gnutls-min-prime-bits} variable is a pretty exotic
 customization for cases where you want to refuse handshakes with keys
