mvn launch script should use jpackage.org config if available
-------------------------------------------------------------

         Key: MNG-2121
         URL: http://jira.codehaus.org/browse/MNG-2121
     Project: Maven 2
        Type: Improvement

  Components: Command Line  
    Versions: 2.0.2    
 Environment: GNU/Linux
    Reporter: Chris Hubick
    Priority: Minor
 Attachments: maven_jpp.patch

I am attempting to install and use Maven for the first time... so excuse me if 
I'm off base here :)

It is my understanding that a single global classpath (and JVM) is generally 
deprecated, so I trivially modified my version of the command line 'mvn' script 
to automatically utilize my existing jpackage.org configuration (patch 
attached).

Also, the installation instructions at http://maven.apache.org/download.html 
say to unpack it to /usr/local/maven-2.0.2/, yet the mvn script looks for the 
existance of /opt/m2/ when attempting to automatically set $M2_HOME.  I 
symlinked /usr/local/maven to /usr/local/maven-2.0.2, and also trivially 
patched my mvn script to look for /usr/local/maven/ when setting $M2_HOME.  
Instead of adding $M2_HOME/bin to my global path, I just symlinked 
/usr/local/bin/mvn -> /usr/local/maven/bin/mvn.  In this way, I have a working 
Maven (I hope) without having to modify any global configuration on my machine 
- meaning the install should be side effect free.  I can also upgrade to a new 
release without having to modify any configuration.
