+#   the main() function has been replaced by a whole class, in order to
+#     address the constraint that only one process can sit on the port
+#     hard-coded into the loader.
+
+#     It attempts to load the RPC protocol server and publish itself.  If
+#     that fails, it assumes that some other copy of IDLE is already running
+#     on the port and attempts to contact it.  It then uses the RPC mechanism
+#     to ask that copy to do whatever it was instructed (via the command
+#     line) to do.  (Think netscape -remote).  The handling of command line
+#     arguments for remotes is still very incomplete.
+
+#   default behavior (no command line options) is to NOT start the Python
+#     Shell.  If files are specified, they are opened, otherwise a single
+#     blank editor window opens.
+
+#   If any command line -options are specified, a shell does appear.  This
+#     is necessary to make the current semantics of the options make sense.
