   As your program gets more involved you might need to create variations on the standard classpath. The Clojure tools supports classpath modifications using aliases, which are parts of the deps file that are only used when the corresponding alias is supplied. Some of the things you can do are:
   
  
positive.code: 
  [source,clojure]
  ----
  {
   :aliases {
     :bench {:extra-deps {criterium {:mvn/version "0.4.4"}}}
   }
  }
  ----
  
  Here the `:bench` alias is used to add an extra dependency, namely the criterium benchmarking library.
  
negative.code: 
  [source,clojure]
  ----
  {:deps
   {org.clojure/core.async {:mvn/version "0.3.465"}}
  
   :aliases
   {:test {:extra-paths ["test"]}}}
  ----
  
  Apply that classpath modification and examine the modified classpath by invoking `clj -C:test -Spath`:
