Description
Dune-deps scans a dune project and produces a dependency graph which can be rendered with 'dot'. It is useful for projects that define multiple libraries or executables. It allows the developer to visualize the dependencies between the various components of a project.

README
dune-deps
Show the internal dependencies in your OCaml/Reason/Dune project.
Input: the root folder of your project
Output: a graph in the dot format
Example:
$ dune-deps | tred > deps.dot
$ dot -Tpng deps.dot -o deps.png
Installation
From opam:
$ opam update
$ opam install dune-deps
From the git repo:
$ make
$ make test
$ make install
Rendering the graph
For producing a 2D image of the graph, we rely on the dot command from Graphviz.
Additionally, it is often desirable to remove excessive edges to make the graph more readable. We consider "excessive" an edge that can be removed without changing the reachability from a node to another. This transformation is called transitive reduction and is performed by tred, normally installed as part of the Graphviz suite.
