+# RPKI Engine Common Configuration Options
+
+Some of the configuration options are common to all of the daemons. Which
+daemon they affect depends only on which sections of which configuration file
+they are in.
+
+The first group of options are boolean flags, which can be set to "true" or
+"false". If not specified, default values will be chosen (generally false).
+Many of these flags controll debugging code that is probably of interest only
+to the developers.
+
+debug_http::
+
+> Enable verbose http debug logging.
+
+want_persistent_client::
+
+> Enable http 1.1 persistence, client side.
+
+want_persistent_server::
+
+> Enable http 1.1 persistence, server side.
+
+use_adns::
+
+> Use asynchronous DNS code. Enabling this will raise an exception if the
+dnspython toolkit is not installed. Asynchronous DNS is an experimental
+feature intended to allow higher throughput on busy servers; if you don't know
+why you need it, you probably don't.
+
+enable_ipv6_clients::
+
+> Enable IPv6 HTTP client code.
+
+enable_ipv6_servers::
+
+> Enable IPv6 HTTP server code. On by default, since listening for IPv6
+connections is usually harmless.
+
+debug_cms_certs::
+
+> Enable verbose logging about CMS certificates.
+
+sql_debug::
+
+> Enable verbose logging about sql operations.
+
+gc_debug::
+
+> Enable scary garbage collector debugging.
+
+timer_debug::
+
+> Enable verbose logging of timer system.
+
+enable_tracebacks::
+
+> Enable Python tracebacks in logs.
+
+There are also a few options which allow you to save CMS messages for audit or
+debugging. The save format is a simple MIME encoding in a
+{{<http://en.wikipedia.org/wiki/Maildir|Maildir}-format> mailbox. The current
+options are very crude, at some point we may provide finer grain controls.
+
+dump_outbound_cms::
+
+> Dump verbatim copies of CMS messages we send to this mailbox.
+
+dump_inbound_cms::
+
+> Dump verbatim copies of CMS messages we receive to this mailbox.
