Having reusable tools in the first place, to make it a problem simple enough to solve with a shell script, is the accomplishment that advances the state of our art. It reduces a complex data structure to passing data through a pipe, which makes the algorithm more usable for more people.

I wrote in a literate programming style for years, to generate LaTeX documents and a world-scale build system for a multinational. But I'm past that, since it's intricate and unmaintainable by others. Instead, I'd rather generate documents in UTF-8 (an ASCII-compatible and increasingly universal format), and sets of small tools which call each other and expose their data in files for new tools to use. With this approach I can evolve the toolset in small, state-preserving steps, to minimize how much I have to code to meet current needs and implement new approaches.
