   1 """SCons.Tool.ipkg
   2
   3 Tool-specific initialization for ipkg.
   4
   5 There normally shouldn't be any need to import this module directly.
   6 It will usually be imported through the generic SCons.Tool.Tool()
   7 selection method.
   8
   9 The ipkg tool calls the ipkg-build. Its only argument should be the
  10 packages fake_root.
