+Plugins
+=======
+
+vlib implements a straightforward plug-in DLL mechanism. VLIB client
+applications specify a directory to search for plug-in .DLLs, and a name
+filter to apply (if desired). VLIB needs to load plug-ins very early.
+
+Once loaded, the plug-in DLL mechanism uses dlsym to find and verify a
+vlib\_plugin\_registration data structure in the newly-loaded plug-in.
