Very basic scripts for drawing a graph of the crates.io packages. Blog post.
make should create something semisensible, code may have to be
edited (the MAX_REV_DEP_COUNT field at the top of src/main.rs) to
reproduce the results shown in the blog post (well, to get closer: the
package system is living and changes).
It requires graphviz (fdp and gvpr) and git at least.
