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.
