"""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.
