-"""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.
