How do create the neat flow diagrams for SQLite?
It turns out that I had to build Sqlite in order to get tclsqlite.c. I was successful in building that and in building the doc files. 

However, my goal is to build my own docs. I can't figure out what the minimum set of files and processes are to get something that works. Can you tell me what that minimum set is and what processes I have to run (by hand) to gen the docs, please?
