+# you use a frame opened in a terminal via a ssh connection or X frames
+# opened on the same host.
+
+# Benefits are multiple
+# - You don't have the cost of starting Emacs all the time anymore
+# - Opening a file is as fast as Emacs does not have anything else to do.
+# - You can share opened buffered across opened frames.
+# - Configuration changes made at runtime are applied to all frames.
