2.5.2.3 GDB Initialization
..........................

 -- Resource: gdbInitCommands (class InitCommands)
     This string contains a list of newline-separated commands that are
     initially sent to GDB.  As a side-effect, all settings specified
     in this resource are considered fixed and cannot be changed
     through the GDB settings panel, unless preceded by white space.
     By default, the `gdbInitCommands' resource contains some settings
     vital to DDD:

            Ddd*gdbInitCommands: \
            set height 0\n\
            set width 0\n\
             set verbose off\n\
            set prompt (gdb) \n

     While the `set height', `set width', and `set prompt' settings are
     fixed, the `set verbose' settings can be changed through the GDB
     settings panel (although being reset upon each new DDD invocation).

     Do not use this resource to customize GDB; instead, use a personal
     `~/.gdbinit' file.  See your GDB documentation for details.

 -- Resource: gdbSettings (class Settings)
     This string contains a list of newline-separated commands that are
     also initially sent to GDB.  Its default value is

            Ddd*gdbSettings: \
            set print asm-demangle on\n

     This resource is used to save and restore the debugger settings.

 -- Resource: sourceInitCommands (class SourceInitCommands)
     If `on' (default), DDD writes all GDB initialization commands into
     a temporary file and makes GDB read this file, rather than sending
     each initialization command separately.  This results in faster
     startup (especially if you have several user-defined commands).  If
     `off', DDD makes GDB process each command separately.
