"""SCons.Tool.sgiar

Tool-specific initialization for SGI ar (library archive).  If CC
exists, static libraries should be built with it, so the prelinker has
a chance to resolve C++ template instantiations.

There normally shouldn't be any need to import this module directly.
It will usually be imported through the generic SCons.Tool.Tool()
selection method.
