Setting global environment in Mac OS X

I just wanted to quote myself on setting the environment variable in Mac OS X.

From, http://stackoverflow.com/questions/135688/setting-environment-variables-in-os-x

This is stated as,

1) Open a terminal prompt

2) Type sudo vi /etc/launchd.conf (note: this file might not yet exist)

3) Put contents like the following into the file

# Set environment variables here so they are available globally to all apps
# (and Terminal), including those launched via Spotlight.
#
# After editing this file run the following command from the terminal to update 
# environment variables globally without needing to reboot.
# NOTE: You will still need to restart the relevant application (including 
# Terminal) to pick up the changes!
# grep -E "^setenv" /etc/launchd.conf | xargs -t -L 1 launchctl
#
# See http://www.digitaledgesw.com/node/31
# and http://stackoverflow.com/questions/135688/setting-environment-variables-in-os-x/
#
# Note that you must hardcode the paths below, don't use enviroment variables.
# You also need to surround multiple values in quotes, see MAVEN_OPTS example below.
#
setenv JAVA_VERSION 1.6
setenv JAVA_HOME /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
setenv GROOVY_HOME /Applications/Dev/groovy
setenv GRAILS_HOME /Applications/Dev/grails
setenv NEXUS_HOME /Applications/Dev/nexus/nexus-webapp
setenv JRUBY_HOME /Applications/Dev/jruby

setenv ANT_HOME /Applications/Dev/apache-ant
setenv ANT_OPTS -Xmx512M

setenv MAVEN_OPTS "-Xmx1024M -XX:MaxPermSize=512m"
setenv M2_HOME /Applications/Dev/apache-maven

setenv JMETER_HOME /Applications/Dev/jakarta-jmeter

4) Save your changes in VI and reboot your Mac. Or use the grep/xargs command show in the code comment above.

5) Prove that your variables are working by opening a Terminal window and typing export and you should see your new variables. These will also be available in IntelliJ and other GUI apps you launch via Spotlight.
