       lein - Automate Clojure projects


       lein [-o] [-U] [TASK [ARGS]]
       lein [-h|--help]
       lein [-v|--version]


       Leiningen is for automating Clojure projects without setting your hair on fire.

       Working  on  Clojure  projects  with  tools  designed  for  Java  can  be  an  exercise in
       frustration. With Leiningen, you just write Clojure.


       lein help will show the complete list of tasks, while lein help TASK  shows  usage  for  a
       specific one.

       commonly-used are:

       Leiningen reads its configuration from the project.clj file in your project  root.  Either
       use  lein  new to create a fresh project from which to work, or see the exhaustive list of
       configuration options with lein help sample.

       You can customize your project map further with profiles; see lein help profiles.
