#
# 2013/10/30 Updated for OS X 10.9.
#
# 2013/05/11 Added a few more guidance when Java Preferences is not available anymore
# Added a simple example of a JDK switch function.
#
# 2012/08/25 This script didn't behave correctly when ran on 10.8.1
# Added recommendation to always run this script after updates such as Java, XCode, OSX, etc.
#
# 2O12/07/29 Added Mountain Lion support => Choose the 64bit JVM !
# Can dowload the Java DMG itself if not present in same directory
# Colored the output a bit, works well on a black background
# Added tips for using the different JVMs
# Removed 32bit mode for Mountain Lion (Thanks to Henri Gomez for pointing me to 'ditto')
#
# 2011/12/04 Added warnings and some more information on gotchas
#
# 2011/08/25 Updated this very comments
#
# 2011/08/22 Initial version (Thanks to Benjamin Morin for his blog post)
# This script heavily inspired/copied from http://www.s-seven.net/java_15_lion

Thank you so much, after 3 hours googling and trying different solutions your script finally worked in 10.9!
