I'll be drawing those graphs by hand today at my Operating Systems
course :) I'll blog them today.

Making a library for transforming the source code into a graph would
help me finish my debugger easier. But the library would have to take
into account the fact that the output graph may be used in a wide
range of ways from debugging to teaching (why not integrate it for
example with LaTeX Beamer and its support for predefined image
