 #
 # This script runs the OpenSSL Configure script, then processes the
 # resulting file list into our local OpensslLib[Crypto].inf and also
 # takes copies of opensslconf.h and dso_conf.h.
 #
 # This only needs to be done once by a developer when updating to a
 # new version of OpenSSL (or changing options, etc.). Normal users
 # do not need to do this, since the results are stored in the EDK2
 # git repository for them.
 #
 # Due to the script wrapping required to process the OpenSSL
 # configuration data, each native architecture must be processed
 # individually by the maintainer (in addition to the standard version):
 #   ./process_files.pl
 #   ./process_files.pl X64
 #   ./process_files.pl [Arch]
 #
 # Follow the command below to update the INF file:
 # 1. OpensslLib.inf ,OpensslLibCrypto.inf and OpensslLibFull.inf
 # ./process_files.pl
 # 2. OpensslLibAccel.inf and OpensslLibFullAccel.inf
 # ./process_files.pl X64
 # ./process_files.pl X64Gcc
 # ./process_files.pl IA32
 # ./process_files.pl IA32Gcc
