# This script imports new versions of Bouncy Castle
# (http://bouncycastle.org) into the Android source tree. To run, (1)
# fetch the appropriate tarballs (bcprov and bcpkix) from the Bouncy
# Castle repository, (2) check the checksum, and then (3) run:
# ./import_bouncycastle.sh import bcprov-jdk*-*.tar.gz
#
# IMPORTANT: See README.android for additional details.
# turn on exit on error as well as a warning when it happens
