Since Emacs 25, Emacs supports loading of modules that extend Emacs
Lisp with additional primitives.  Those modules are shared libraries,
and can be written in any language that is capable of producing shared
libraries.  Loading of such modules by Emacs is subject to checking
the plugin_is_GPL_compatible symbol in the library about to be loaded.
