Seems odd to put this all into the same namespace.  Maybe we should be able to
control the namespace from GN?

+    f.write('namespace {\n')
+    f.write("const char data[%d] = {\n" % len(data))
+    f.write(",\n".join(lines))
+    f.write("\n};\n")
+    f.write('}  // namespace\n')
+    f.write('\n')
+    f.write('extern const mojo::embed::Data %s;\n' % opts.variable);
+    f.write('const mojo::embed::Data %s = {\n' % opts.variable);
+    f.write('  "%s",\n' % sha1hash)
+    f.write('  data,\n')
+    f.write('  sizeof(data)\n')
+    f.write('};\n');
+    f.write('\n')
+    f.write('}  // namespace embed\n')
