-/** Provides low-level, relatively platform-independent access to
-    shared ("native") libraries. The core library routines
-    <code>System.load()</code> and <code>System.loadLibrary()</code>
-    in general provide suitable functionality for applications using
-    native code, but are not flexible enough to support certain kinds
-    of glue code generation and deployment strategies. This class
-    supports direct linking of native libraries to other shared
-    objects not necessarily installed on the system (in particular,
-    via the use of dlopen(RTLD_GLOBAL) on Unix platforms) as well as
-    manual lookup of function names to support e.g. GlueGen's
-    ProcAddressTable glue code generation style without additional
-    supporting code needed in the generated library. */
