That suggests I'd be following the grap route, creating a pic preprocessor. Some details are very different. Font control, for instance. pic relies on troff, and pikchr has its own syntax. I don't know how to intercept the PS/PE macros in mandoc to invoke pikchr. It seems like writing my own PS/PE macros would be a start (a first for me). If possible, I want to avoid writing wrappers; I prefer to work within the groff and mandoc frameworks. That would make the work easier for others to use, should I get that far. > Niklaus Wirth used railroad diagrams in the Pascal User Manual and > Report, and I always found them very helpful [....] That puts us in good company, doesn't it?
