|sysconfdir|\ ``/gss/mech.d`` directory with a ``.conf``
suffix. Each line in these files has the form::
- oid pathname [options] <type>
-
-Only the oid and pathname are required. *oid* is the object
-identifier of the GSSAPI mechanism to be registered. *pathname* is a
-path to the module shared object or DLL. *options* (if present) are
-options provided to the plugin module, surrounded in square brackets.
-*type* (if present) can be used to indicate a special type of module.
-Currently the only special module type is "interposer", for a module
-designed to intercept calls to other mechanisms.
+ name oid pathname [options] <type>
