I Will Break Your Unit Testes (tm)

How much does it cost to develop a debugger? I ran SLOC Count on the source tree of my ZeroBUGS debugger for Linux, which I have been developing single-handedly since 2003 (late Fall).

I have removed some of the third party components, such as libdwarf and Google's sparsehash, but I kept all experimental and support code (you can subtract the ansi C lines though, they represent some old tests).

I don't know what else to read into this, other than I am a badass.

You think that cowboy programming is bad?

I believe that agile is well suited for developers with small unit testes.
