Adjectives describe nouns, in the quoted text that is "interface secrets". The quoted text did not refer to output/results. The quote of my function to draw a door in a floorplan shows my text input, not output/results. The result of conversion of the postscript to pdf is a suite of drawings when displayed with e.g. xpdf. (Scrutable even to local government officials, at considerable cost saving compared to using an architect.) But there is perhaps an unstated point - that the postscript language (the interface) is not equally scrutable for all. I found it infinitely easier to learn a fully discoverable textual language than how to crank a mouse engine in mysterious ways. Eric Raymond perhaps said it best. (See sig) Cheers, Erik -- The meta-problem here is that the configuration wizard does all the approved rituals (GUI with standardized clicky buttons, help popping up in a browser, etc. etc.) but doesn't have the central attribute these are supposed to achieve: discoverability. That is, the quality that every point in the interface has prompts and actions attached to it from which you can learn what to do next. - Eric Raymond, in "The Luxury of Ignorance."
