# wolfSSL and wolfSSL JNI AOSP Install Script
#
# This script will install necessary source files from the wolfSSL C library
# source directory and the wolfSSL JNI source directory into an Android
# OSP (Open Source Project) working source tree.
#
# This script is used as one step to install wolfJSSE as an alternate SSL/TLS
# Security Provider into Android AOSP.
#
# Before using this script, please read:
#
#     1) README.android_asop (located in this same directory)
#     2) "Installing a JSSE Provider in Android AOSP" document, by wolfSSL
