-Off-load dependency scanning from Python code to MSVC compiler
-
-This tool is safe to load in any environment; it will only activate the
-MSVC exploits when it finds that a particular taskgen uses MSVC to
-compile.
-
-Empirical testing shows about a 10% execution time savings from using
-this tool as compared to c_preproc.
-
-The technique of gutting scan() and pushing the dependency calculation
-down to post_run() is cribbed from gccdeps.py.
-
-This affects the cxx class, so make sure to load Qt5 after this tool.
-
-Usage::
-
-	def options(opt):
-		opt.load('compiler_cxx')
-	def configure(conf):
-		conf.load('compiler_cxx msvcdeps')
