"""SCons.Tool.icl
|
||
|
|
|
||
|
|
Tool-specific initialization for the Intel C/C++ compiler.
|
||
|
|
Supports Linux and Windows compilers, v7 and up.
|
||
|
|
|
||
|
|
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.
