- We block! debugger is on the way you go.

The GNU project started by building a toolkit, uh, basic development tools such as a C compiler, a debugger, a text-editor, and uh, other necessary apparatus.

Well... we had to... to have a complete system, you need to have a kernel, which is the program that allocates resources to all the other programs, you need a compiler, which translates a program from readable source code that programmers can understand into numbers, mysterious numbers that the computer can actually run. you need other programs that go with the compiler to help do this job. you need a debugger. you need a text editor. you need text formatters. you need mailers... you need lots and lots of things.
