+# This script builds the iOS and Mac openSSL libraries
+# Download openssl http://www.openssl.org/source/ and place the tarball next to this script

+# Dave Nottage, RADSoft, @DelphiWorlds
+
+# Updated to work with Xcode 8.3.3 and iOS 10
+# This script is significantly modified from the original (as per the links above)
+# It generates dylibs for i386 and x86_64 architectures, and can be used on iOS simulator only
+# The selected version of the OpenSSL source must be expanded first, and the Makefile.shared file modified to suit
