[Sergey Ulanov, 2016/06/09 23:37:30]

If I understand correctly this comment is the reason you added version.h.in. But
the GN still need to load these parameters as me2me_host_bundle_name. You fixed
remoting_version.gni to invoke python only once, which is great. But as long as
we still load these in GN it's better to pass them to the build using defines
instead of generated header.

[nicholss, 2016/06/10 16:40:31]

They are set by importing on remoting_versiong.gni and a bit of magic from
//build/util/version.py

So I think this is ok.

-      # Note if you are looking at this: It really sucks to have to synchronously
-      # call into python twice to get these values. They should instead be
-      # written into a generated header via the process_version template, and we
-      # change the source files to include that header rather than rely on these
-      # defines being set in the build.
-      #defines += [
-      #  "HOST_BUNDLE_NAME=\"$host_bundle_name\"",
-      #  "PREFPANE_BUNDLE_NAME=\"$prefpane_bundle_name\"",
