-;;; Change Log:
-
-;; Version 1.1:                ESR     6 Apr 1993
-;;   * Facility to accept and parse command-line switches other than the
-;;     filename added.
-;;   * System V Release 4 support added.
-;;   * Can now set temporary breakpoints in sdb.
-;;   * A GUD minor mode using the 19 minor-mode-keymap facilities is now
-;;     enabled in visited C buffers.
-;;   * Command bindings are now automatically the same in gud-minor-mode
-;;     as they are in the GUD buffer itself, and use ^XX as a common
-;;     prefix (for compatibility with electric-debug).
-;;   * There is a new command for printing the C expression around point.
-
-;; Version 1.0:                ESR
-;;   * Created.
