TCl-thread graphs (was: Re: Scipad debugger)

[Enrico Segre]

Well well, not that I'm very happy about this hasty disabling of the 
debugger, after we've been inquiring about for months. At least I take 
for it that it was not intended a  deliberate sabotage, as we could have 
been led to think, and that dialog finally restarts. It might be a 
matter of finding common language, but at least I see some hint of a 
will of sharing information.

I was on holiday until last week, and still have to find some time to 
digest the new information.

Anyway, first question, about the new (at least!) flowcharts in 
http://wiki.scilab.org/Tcl_Thread : the various boxes of the state 
machines have some functional characterization besides their numerical 
labels? With what were the graphs produced, in case we want to suggest, 
graphically, new structures? Though I understand it, I'm not familiar 
with the graphical notation of the flowcharts currently on wiki; could 
you send me a pointer for the scheme (I guess it is a standard one) used?

Not seeing these graphs, I was once considering to produce them with 
graphviz, decoding the previous content of the wiki page. I stopped at 
some point for lack of time, but for reference I attach what I managed 
to do (certainly unfinished and with errors, but possibly a little more 
descriptive?).
