+#REGTEST_TYPE=devel
+
+# This reg-test checks that the 'generate-certificates' SSL option works
+# properly. This option allows to generate server-side certificates on the fly
+# for clients that use an SNI for which no certificate was specified in the
+# configuration file.
+# This test also aims at checking that the 'generate-certificates' and the
+# 'ecdhe' bind options work correctly together.
+# Any bind line having a 'generate-certificates' needs to have a ca-sign-file
+# option as well that specifies the path to a CA pem file (containing a
+# certificate as well as its private key). For this reason, a new
+# ssl_gen_ca.pem CA certificate was created, along with the ssl_gen_server.pem
+# server certificate signed by the CA. This server certificate will be used as
+# a default certificate and will serve as a base for any newly created
+# certificate.
