+    \item[\code{posix-syscalls}] Provides and demonstrates the
+      scaffolding for extending the implementation by use of direct
+      syscalls via the foreign function interface (FFI) afforded by
+      the JNA library.  Upon loading this system, new implementations
+      of the \code{EXT:GETENV} and \code{UIOP/OS:GETENV} functions are
+      installed which use FFI to directly call the \sc{posix} syscalls
+      where available, which allows environment variables to be set.
