* Remove the TTY mode and TTY window from CGDB. This previously allowed
you to send input to the program being debugged through the TTY
window in CGDB. It is better for the user to run their program in
one terminal and attach to it with CGDB from another terminal in
order to get terminal input and terminal output working correctly.
* Add the -w command line option to CGDB. It directs CGDB to wait
to start until either a debugger is attached to it, or until a key
is written to it's stdin. This helps simplify debugging CGDB itself.
But I don't how to use cgdb options: -w
Please help.Thank you!
