+    R"(gn format [--dump-tree] (--stdin | <build_file>)
+
+  Formats .gn file to a standard format.
+
+  The contents of some lists ('sources', 'deps', etc.) will be sorted to a
+  canonical order. To suppress this, you can add a comment of the form "#
+  NOSORT" immediately preceeding the assignment. e.g.
+
+  # NOSORT
+  sources = [
+    "z.cc",
+    "a.cc",
+  ]
+
+Arguments
+
+  --dry-run
+      Does not change or output anything, but sets the process exit code based
+      on whether output would be different than what's on disk. This is useful
+      for presubmit/lint-type checks.
+      - Exit code 0: successful format, matches on disk.
+      - Exit code 1: general failure (parse error, etc.)
+      - Exit code 2: successful format, but differs from on disk.
+
+  --dump-tree
+      For debugging, dumps the parse tree to stdout and does not update the
+      file or print formatted output.
+
+  --stdin
+      Read input from stdin and write to stdout rather than update a file
+      in-place.
+
+Examples
+  gn format //some/BUILD.gn
+  gn format some\\BUILD.gn
+  gn format /abspath/some/BUILD.gn
