# The original intent of this script was to install the unlimited strength JCE
# to *all* Oracle JDKs installed on the system. With the advent of the JCE
# being delivered within the JDK, and the added complexity of trying to
# determine versions, this script *will not* install the JCE at all if it sees
# JDK 1.8.0_151 or newer. This script *will* configure JDK 1.8.0_151 -
# 1.8.0_160 to enable the unlimited policy.
# Function to discover basic OS details.
