# Provides a function that allows you to choose a JDK.  Just set the environment 
# variable JDKS_ROOT to the directory containing multiple versions of the JDK
# and the function will prompt you to select one.  JAVA_HOME and PATH will be cleaned
# up and set appropriately.

# Usage:
# Include in .profile or .bashrc or source at login to get 'pickjdk' command.
# 'pickjdk' alone to bring up a menu of installed JDKs on OS X. Select one.
