+
+  See also "gn help buildargs" for a more high-level overview of how
+  build arguments work.
+
+Usage
+  gn args <out_dir>
+      Open the arguments for the given build directory in an editor (as
+      specified by the EDITOR environment variable). If the given build
+      directory doesn't exist, it will be created and an empty args file will
+      be opened in the editor. You would type something like this into that
+      file:
+          enable_doom_melon=false
+          os="android"
+
+      Note: you can edit the build args manually by editing the file "args.gn"
+      in the build directory and then running "gn gen <out_dir>".
+
+  gn args <out_dir> --list[=<exact_arg>] [--short]
+      Lists all build arguments available in the current configuration, or, if
+      an exact_arg is specified for the list flag, just that one build
+      argument.
+
+      The output will list the declaration location, default value, and comment
+      preceeding the declaration. If --short is specified, only the names and
+      values will be printed.
+
+      If the out_dir is specified, the build configuration will be taken from
+      that build directory. The reason this is needed is that the definition of
+      some arguments is dependent on the build configuration, so setting some
+      values might add, remove, or change the default values for other
+      arguments. Specifying your exact configuration allows the proper
+      arguments to be displayed.
+
+      Instead of specifying the out_dir, you can also use the command-line flag
+      to specify the build configuration:
+        --args=<exact list of args to use>
+
+Examples
+
+  gn args out/Debug
+    Opens an editor with the args for out/Debug.
+
+  gn args out/Debug --list --short
+    Prints all arguments with their default values for the out/Debug
+    build.
+
+  gn args out/Debug --list=target_cpu
+    Prints information about the "target_cpu" argument for the "
+   "out/Debug
+    build.
+
+  gn args --list --args="os=\"android\" enable_doom_melon=true"
+    Prints all arguments with the default values for a build with the
+    given arguments set (which may affect the values of other
+    arguments).
