Poor man's sequence diagrams


An old piece of code to draw sequence-diagram-ish.

I resumed some code from about 13 years ago… and polished it a bit, but not completely. It’s a toy to draw sequence diagrams, that lived within a module designed for my computer science engineering thesis.

The code (a local version is here) is the following:
