If the :main directive is defined in the project.clj file of the project, then the project can be run by directly calling the lein run command. lein run expects the namespace specified under :main directive to contain the Clojure main function. For example, the playground.core namespace must have a main function defined for lein run to work, as shown in the following implementation.
