+* How can I set up a bundle of commercial root CA certificates?
+
+The OpenSSL software is shipped without any root CA certificate as the
+OpenSSL project does not have any policy on including or excluding
+any specific CA and does not intend to set up such a policy. Deciding
+about which CAs to support is up to application developers or
+administrators.
+
+Other projects do have other policies so you can for example extract the CA
+bundle used by Mozilla and/or modssl as described in this article:
