 
       $ mix xref graph --label compile --sink lib/c.ex
       lib/a.ex
-      `-- lib/b.ex (compile)
+      └── lib/b.ex (compile)
 
   ### Dependencies types
 


      $ mix xref graph --label compile
      lib/a.ex
      `-- lib/b.ex (compile)
      lib/b.ex
      `-- lib/c.ex

  In other words, when using `--label compile`, any dependency on the graph
  without the "(compile)" label is a transitive compile time dependency.


  The `xref` task expects a mode as first argument:

      $ mix xref MODE

  All available modes are discussed below.
