# 2013/06/10 Tested on Mountain Lion 10.8.4
# 2013/02/14 Updated to run on Mountain Lion 10.8.2
# 
# 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
