  30 # This example is suitable for building an illumos workspace, which
  31 # will contain the resulting archives. It is based off the onnv
  32 # release. It sets NIGHTLY_OPTIONS to make nightly do:
  33 #       DEBUG build instead of non-DEBUG (-D)
  34 #       runs 'make check' (-C)
  35 #       checks for new interfaces in libraries (-A)
  36 #       sends mail on completion (-m and the MAILTO variable)
  37 #       creates packages for PIT/RE (-p)
  38 #       checks for changes in ELF runpaths (-r)
