   1 """SCons.Tool.sgiar
   2
   3 Tool-specific initialization for SGI ar (library archive).  If CC
   4 exists, static libraries should be built with it, so the prelinker has
   5 a chance to resolve C++ template instantiations.
   6
   7 There normally shouldn't be any need to import this module directly.
   8 It will usually be imported through the generic SCons.Tool.Tool()
   9 selection method.
