+WARNING WARNING WARNING!!!
+
+This stuff is experimental, may change radically or be deleted altogether
+before OpenSSL 0.9.7 release. You have been warned!
+
+Configuration modules. These are a set of modules which can perform
+various configuration functions.
+
+Currently the routines should be called at most once when an application
+starts up: that is before it starts any threads.
+
+The routines read a configuration file set up like this:
+
+-----
+#default section
+openssl_init=init_section
+
+[init_section]
+
+module1=value1
+#Second instance of module1
+module1.1=valueX
+module2=value2
+module3=dso_literal
+module4=dso_section
+
+[dso_section]
+
+path=/some/path/to/some/dso.so
+other_stuff=other_value
+----
+
+When this file is loaded a configuration module with the specified
+string (module* in the above example) is looked up and its init
+function called as:
+
+int conf_init_func(CONF_IMODULE *md, CONF *cnf);
+
+The function can then take whatever action is appropriate, for example
+further lookups based on the value. Multiple instances of the same
+config module can be loaded.
+
+When the application closes down the modules are cleaned up by calling
+an optional finish function:
+
+void conf_finish_func(CONF_IMODULE *md);
+
+The finish functions are called in reverse order: that is the last module
+loaded is the first one cleaned up.
+
+If no module exists with a given name then an attempt is made to load
+a DSO with the supplied name. This might mean that "module3" attempts
+to load a DSO called libmodule3.so or module3.dll for example. An explicit
+DSO name can be given by including a separate section as in the module4 example
+above.
+
+The DSO is expected to at least contain an initialization function:
+
+int OPENSSL_init(CONF_IMODULE *md, CONF *cnf);
+
+and may also include a finish function:
+
+void OPENSSL_finish(CONF_IMODULE *md);
+
+Static modules can also be added using,
+
+int CONF_module_add(char *name, dso_mod_init_func *ifunc, dso_mod_finish_func *ffunc);
+
+where "name" is the name in the configuration file this function corresponds to.
+
+A set of builtin modules (currently only an ASN1 non functional test module) can be
+added by calling OPENSSL_load_builtin_modules().
+
+The function OPENSSL_config() is intended as a simple configuration function that
+any application can call to perform various default configuration tasks. It uses the
+file openssl.cnf in the usual locations.
