CryptoPkg: Separate auto-generated openssl config and edk2 openssl config

[mirror_edk2.git] / CryptoPkg / Library / OpensslLib / process_files.pl

#!/usr/bin/perl -w\r
#\r
# This script runs the OpenSSL Configure script, then processes the\r
# resulting file list into our local OpensslLib[Crypto].inf and also\r
# takes copies of opensslconf.h and dso_conf.h.\r
#\r
# This only needs to be done once by a developer when updating to a\r
# new version of OpenSSL (or changing options, etc.). Normal users\r
# do not need to do this, since the results are stored in the EDK2\r
# git repository for them.\r
#\r
# Due to the script wrapping required to process the OpenSSL\r
# configuration data, each native architecture must be processed\r
# individually by the maintainer (in addition to the standard version):\r
#   ./process_files.pl\r
#   ./process_files.pl X64\r
#   ./process_files.pl [Arch]\r
