I started with your first article which begins with "There aren't any debuggers for Make"
Actually Rocky's remake existed in June 2004 already. Bad, very bad...

Initial revision
Hmm. "Bad, very bad..." seems like an exaggeration. I wrote that article in June 2004. Although the initial commit for remake (which I covered in 2007) was in April 2004 the initial release was... at the same time as my article.
