“Blessed are the toolmakers”: the original article focuses on the ability to build your own tools. The follow up praises the perl tool-smiths and their sense of play for creating tools for (almost) every problem that arises. I fully agree. And hence, I should turn my little script from my past article into a tool. But isn’t it already one? – Both authors fail to give a definition of what a good tool is like. A good tool serves one purpose. And it serves it well, even when used in unforeseen ways. So it has to be hardened against unpleasant working conditions and must be predictable under all circumstances. This is where most scripts and ad-hoc programs fail, my little script being no exception. So blessed are the toolmakers who can craft useful and efficient tools!
