How are the syntax diagrams (a.k.a. "railroad" diagrams) for SQLite generated?

The wiki links to this Tcl source code for generating the diagrams.

That is a syntax diagram. I think I first saw them in Grogono's "Programming in Pascal", from 1980, but they were used in Wirth's 1973 report on PASCAL.

Just a hint for LaTeX-Users:

The rail-package allows the generation of such rail-diagramms with (La)TeX.

You may check TeX.SX for an example.
