Running make in this directory will generate a number of PDF graphs.

In the callgraph, the arrows means "calls". In the dependency graphs,

the arrows means "requires" (or "depends upon").

callgraph.pdf This shows the callgraph, i.e., what functions each

function in the program calls.

module_dependencies.pdf This shows the dependencies between the modules.

file_dependencies.pdf This shows the dependencies between the files.

makefile_dependencies.pdf This shows the dependencies required by make when

building the program.

build_dependencies.pdf This is like makefile_dependencies.pdf but shows

the operations performed to generate the new file.

callgraph.d This shows the callgraph in text format.
