hurd/Notes

   1 The library pays attention to some envariables:
   2
   3 CORESERVER     -- Name of core server naming point; falls back to /servers/core
   4 COREFILE       -- Name of file to write core dump in; falls back to core
   5 GNUTARGET      -- Passed to core server to specify flavor of core dump format
