+ *
+ * The fuzzer corpus generated as first input was generated with the
+ * following parameters for gnutls-serv and gnutls-cli:
+ *
+ * gnutls-serv --priority NORMAL:+CTYPE-CLI-RAWPK:+CTYPE-SRV-RAWPK
+ * gnutls-cli localhost:5556 --priority NORMAL:-CTYPE-ALL:+CTYPE-CLI-RAWPK:+CTYPE-SRV-RAWPK --no-ca-verification
