+;; GDB developers plan to make the annotation interface obsolete. A new
+;; interface called GDB/MI (machine interface) has been designed to replace
+;; it. Some GDB/MI commands are used in this file through the CLI command
+;; 'interpreter mi <mi-command>'. A file called gdb-mi.el is included in the
+;; GDB repository for future releases (6.2 onwards) that uses GDB/MI as the
+;; primary interface to GDB. It is still under development and is part of a
+;; process to migrate Emacs from annotations to GDB/MI.
