# This script will attempt to build and install the necessary CLDR JAR files
# from a given CLDR installation root directory. The JAR files are installed
# according to the manual instructions given in README.txt and lib/README.txt.
#
# The user must have installed both 'ant' and 'maven' in accordance with the
# instructions in README.txt before attempting to run this script.
#
# Usage (from the directory of this script):
#
# ./install-cldr-jars.sh <CLDR-root-directory>
#
# Note to maintainers: This script cannot be assumed to run on a Unix/Linux
# based system, and while a Posix compliant bash shell is required, any
# assumptions about auxiliary Unix tools should be minimized (e.g. things
# like "dirname" or "tempfile" may not exist). Where bash-only alternatives
# have to be used, they should be clearly documented.
