-This script builds a GN executable targeting the host machine.
-
-It is useful, for example, for mobile devices performance testing where
-it makes sense to build WebRTC for a mobile platform (e.g. Android) but
-part of the test is performed on the host machine (e.g. running an
-executable to analyze a video downloaded from a device).
-
-The script has only one (mandatory) option: --executable_name, which is
-the output name of the GN executable. For example, if you have the
-following executable in your out folder:
-
-  out/Debug/random_exec
-
-You will be able to compile the same executable targeting your host machine
-by running:
-
-  $ python tools_webrtc/executable_host_build.py --executable_name random_exec
-
-The generated executable will have the same name as the input executable with
-suffix '_host'.
-
-This script should not be used standalone but from GN, through an action:
-
-  action("random_exec_host") {
-    script = "//tools_webrtc/executable_host_build.py"
-    outputs = [
-      "${root_out_dir}/random_exec_host",
-    ]
-    args = [
-      "--executable_name",
-      "random_exec",
-    ]
-  }
-
-The executable for the host machine will be generated in the GN out directory
-(e.g. out/Debug in the previous example).
