Are there any good tools for examining Makefiles? [closed]

Question

Large complex make files can be daunting to read and examine. What tools are good for visualizing or otherwise examining a gnu make file?

Answer 1

I tried to use CPAN's visualizer and failed. So, I've written my own quick-n-dirty Makefile visualizer.

Answer 2

There is a Perl library for building GraphViz figures from Makefiles:
