"""SCons.Tool SCons tool selection. This looks for modules that define a callable object that can modify a construction environment as appropriate for a given tool (or tool chain). Note that because this subsystem just *selects* a callable that can modify a construction environment, it's possible for people to define their own "tool specification" in an arbitrary callable function. No one needs to use or tie in to this subsystem in order to roll their own tool definition.
