I was in the process of preparing a TiddlyWiki instance (a BASIC Anywhere Machine"User Guide"), and I figured might as well just start with a copy of the BASIC Anywhere Machine Programming Reference and strip away what I don’t want so that I am left with just the architectural things (organization, presentation, etc.) for documentation.
It didn’t take me long to realize that what I had was a proper TiddlyWiki starter file for any kind of documentation, including documentation about how to use the starter file.
If of interest to anybody for study/whatever, I’ll be slowly putting together the BASIC Anywhere Machine Documentation Starter (i.e. the “empty.html”) and the BASIC Anywhere Machine Documentation Guide (i.e. how to use the documentation starter and create documentation; nothing there yet).
