# Run './build/debug/mag --client=ncurses $*' inside GDB.  This spawns a split screen
# layout inside tmux with GDB at the top and Mag at the bottom.  Arguments are forwarded
# through to Mag.  If this script is ran inside tmux it will take over the existing tmux
# window.  If it is ran from outside tmux, it will create a new tmux window automatically.
#
# GUI clients do not require a test harness because the graphics component
# doesn't interact with the command line.  But TUI clients such as ncurses take
# over the command line and thus cannot be used with a normal GDB instance.
