Egypt is a simple tool for creating call graphs of C programs. Egypt
neither analyzes source code nor lays out graphs. Instead, it leaves the
source code analysis to GCC and the graph layout to Graphviz, both of
which are better at their respective jobs than egypt itself could ever
hope to be. Egypt is simply a very small Perl script that glues these
existing tools together.
