Clojure POM for Maven2
======================
Q: A Maven POM for Clojure ?!?
> Yes. Don't run away with your hair on fire. This is only used for dependency
management (and optionaly AOT compile clojure into java classes).
Q: How do I get started ?
> It's easy. Just follow the steps below and you'll
have access to tens of thousands of Java libraries inside Clojure
* Make sure you have > Java5 on your box
* Install Maven [ https://maven.apache.org ]
* Install Clojure Contrib & POM with git & maven.
  You can find maven-friendly repos on my github account.
NOTE: Clojure 1.0.0 is now on the maven repos officially
git clone git://github.com/dysinger/clojure-pom.git
cd clojure-pom
mvn install
cd ..
git clone git://github.com/dysinger/clojure-contrib.git
cd clojure-contrib
git checkout -b 1.0-SNAPSHOT origin/1.0-SNAPSHOT
mvn install
cd ..
* Now create a new clojure project.  You can create maven archetypes
  if your maven-fu is brown-belt or above.
  Sometimes good ol' 'here' files are easier. I do it like this.
mkdir my-project
cd my-project

Q: How can I use this in Emacs & Slime ?
> Most of us use emacs 23 (trunk) and slime (trunk) with
Philip Hagelberg's emacs-starter-kit.  I won't cover all that here.
It's on github.  https://github.com/technomancy/emacs-starter-kit
Ask about setup particulars on IRC.  It's rapidly evolving.
