+# HOW MANIFESTS WORK IN THE GN BUILD
+#
+# Use the windows_manifest template to declare a manifest generation step.
+# This will combine all listed .manifest files. To link this manifest, just
+# depend on the manifest target from your executable or shared library.
+#
+# This will define an empty placeholder target on non-Windows platforms so
+# the manifest declarations and dependencies do not need to be inside of OS
+# conditionals.
+#
+# A binary can depend on only one manifest target, but the manifest target
+# can depend on many individual .manifest files which will be merged. As a
+# result, only executables and shared libraries should depend on manifest
+# targets. If you want to add a manifest to a component, put the dependency
+# behind a "if (is_component_build)" conditional.
+#
+# Generally you will just want the defaults for the Chrome build. In this case
+# the binary should just depend on one of the targets in //build/win/. There
+# are also individual manifest files in that directory you can reference via
+# the *_manifest variables defined below to pick and choose only some defaults.
+# You might combine these with a custom manifest file to get specific behavior.
+
+# Reference this manifest as a source from windows_manifest targets to get
+# the default Chrome OS compatibility list.
+default_compatibility_manifest = "//build/win/compatibility.manifest"
+
+# Reference this manifest as a source from windows_manifest targets to get
+# the default Chrome common constrols compatibility.
+common_controls_manifest = "//build/win/common_controls.manifest"
+
+# Reference this manifest to request that Windows not perform any elevation
+# when running your program. Otherwise, it might do some autodetection and
+# request elevated privileges from the user. This is normally what you want.
+as_invoker_manifest = "//build/win/as_invoker.manifest"
+
+# An alternative to as_invoker_manifest when you want the application to always
+# elevate.
