Add a Python script that draws dependency graphs, either for the full
set of selected packages, or for a particular given package. Of
course, it is limited to packages that use either the generic or
autotools infrastructures. The script generates a file that Graphviz
can parse and generate a PDF (or other formats) from it.
Full dependency graph of all selected packages :
./scripts/graph-depends > test.dot
dot -Tpdf test.dot -o test.pdf
Dependency graph of libgtk2 :
./scripts/graph-depends libgtk2 > test.dot
dot -Tpdf test.dot -o test.pdf
