Richard Stallman lecture at the Royal Institute of Technology, Sweden (1986-10-30). (abgerufen am 9.Oktober 2019): „Then after GNU Emacs was reasonably stable, which took all in all about a year and a half, I started getting back to other parts of the system. I developed a debugger which I called GDB which is a symbolic debugger for C code, which recently entered distribution. Now this debugger is to a large extent in the spirit of DBX, which is a debugger that comes with Berkeley Unix.“
