   The deps are a map of library to coordinate. The library is (in Maven terms) the groupId and artifactId, which are sufficient to locate the desired project. The coordinate is used to describe a particular version that is being requested from a particular provider (like Maven).
   
  -For example, this deps map specifies two (Maven-based) dependencies:
  -
  -[source,clojure]
  -----
  -{
  -  org.clojure/clojure {:mvn/version "1.9.0"}
  -  org.clojure/core.cache {:mvn/version "0.6.5"}
  -}
  +For example, this deps map specifies a (Maven-based) dependency:
  +
  +[source,clojure]
  +----
  +{org.clojure/core.cache {:mvn/version "0.6.5"}}
   ----
   
   `resolve-deps` expands these dependencies to include all transitive dependencies, cut cycles, resolve version differences, download required artifacts from the provider, and produce a *lib map* of the flattened set of all needed dependencies and where to find their artifacts:
   
   [source,clojure]

  - org.clojure/clojure           {:mvn/version "1.8.0"
  -                                :paths [".../clojure-1.8.0.jar"]}
  - org.clojure/core.cache        {:mvn/version "0.6.5"

  -                                :paths [".../data.priority-map-0.0.7"]
  -                                :dependents [org.clojure/core.cache]}

  + ... }

   The lib map lists all libraries, their selected coordinates, the `:paths` on disk, and a list of dependents that caused it to be included. Here you can see that `data.priority-map` was included as a dependency of core.cache.
