+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')
