gdb - customize it the way <b>you</b> want

'info break' shows the list of currently defined program break-points.
'break <line>' will put a break-point in the given line of the current source file.
'break <function> will put a break-point at the first instruction of the given function.
...'break main' is a good way to allow you to debug step-by-step from the first instruction of the program...
...except for global variables initialization in C++ programs.
'delete <break-point number>' will delete the given breakpoint.
'delete' will delete all existing break-points.
