I'm working on an answer to this question:
30

Consider the following MWE, test.tex: \documentclass[12pt]{article} \begin{document} \tracingassigns=1 \tracingmacros=1 \def\aaa{something} \def\bbb{else \aaa, else} \edef\ccc{third \bbb, level} \tracingassigns=0 \tracingmacros=0 \end{document} If you build this with pdflatex test.tex - ...

The result is a LaTeX package for pretty-printing trace log files which parses the information given about the processing state and actions performed and generates a more informative view with a lot of navigation links, bookmarks etc (I expect this only works with pdflatex in pdf mode at the moment).
Download also bazaar.launchpad.net/~tex-sx/tex-sx/development/view/head:/… (to make a nice long log file) and then run pdflatex twice on bazaar.launchpad.net/~tex-sx/tex-sx/development/view/head:/… to get the test output.
