Subject: [PATCH] * Purification of JDK 5.  At runtime it now uses the
 Nix-deployed   Glibc and X11 client libraries.  The latter are actually
 optional   dependencies: if the function is called with `swingSupport' set to
   `false', they are not needed.  This is nice for, e.g., server  
 environments.

  All hail Patchelf!
