@echo off

rem WORKS ONLY with Leiningen 1.1.0 or newer

rem this script works after downloading Leiningen standalone jar
rem from http://github.com/downloads/technomancy/leiningen/leiningen-VERSION-standalone.jar
rem and copying it on %LEIN_JAR% path

rem optionally can be downloaded also Clojure jar 
rem (stable release, 1.1.0 or newer is recommended)
rem from http://build.clojure.org/releases/
rem and copied on %CLOJURE_JAR% path
rem this step is not necessary, because Leiningen standalone jar
rem contains Clojure as well

set CLOJURE_VERSION=1.1.0
set LEIN_VERSION=1.1.0

rem uncomment this and set paths explicitly 
rem set LEIN_JAR=C:\Documents and Settings\wojcirob\.m2\repository\leiningen\leiningen\%LEIN_VERSION%\leiningen-%LEIN_VERSION%-standalone.jar
