Display complete dependency tree with Leiningen

You can generate Maven's POM out of Leiningen's project definition and then use Maven's dependency:tree plugin with a verbose option, like this:

$ lein pom
$ mvn dependency:tree -Dverbose=true 

This will list dependencies omitted for various reasons, e.g.:

|  +- ring:ring-core:jar:1.4.0:compile
|  |  +- (org.clojure:clojure:jar:1.5.1:compile - omitted for conflict with 1.7.0)
|  |  +- (org.clojure:tools.reader:jar:0.9.1:compile - omitted for conflict with 0.10.0-alpha3)
|  |  +- (ring:ring-codec:jar:1.0.0:compile - omitted for duplicate)

For more options to dependency:tree see its documentation.

This can now be done using leiningen by lein deps :tree. Note the space between deps and :tree.
