#
# --config add the given configuration file, which will be read after
# any "Configurations*" files that are found in the same
# directory as this script.
# --prefix prefix for the OpenSSL installation, which includes the
# directories bin, lib, include, share/man, share/doc/openssl
# This becomes the value of INSTALLTOP in Makefile
# (Default: /usr/local)
# --openssldir OpenSSL data area, such as openssl.cnf, certificates and keys.
# If it's a relative directory, it will be added on the directory
# given with --prefix.
# This becomes the value of OPENSSLDIR in Makefile and in C.
# (Default: PREFIX/ssl)
#
# --cross-compile-prefix Add specified prefix to binutils components.
#
# --api One of 0.9.8, 1.0.0 or 1.1.0. Do not compile support for
# interfaces deprecated as of the specified OpenSSL version.
#
# no-hw-xxx do not compile support for specific crypto hardware.
# Generic OpenSSL-style methods relating to this support
# are always compiled but return NULL if the hardware
# support isn't compiled.
# no-hw do not compile support for any crypto hardware.
# [no-]threads [don't] try to create a library that is suitable for
# multithreaded applications (default is "threads" if we
# know how to do it)
# [no-]shared [don't] try to create shared libraries when supported.
# no-asm do not use assembler
# no-dso do not compile in any native shared-library methods. This
# will ensure that all methods just return NULL.
# no-egd do not compile support for the entropy-gathering daemon APIs
# [no-]zlib [don't] compile support for zlib compression.
# zlib-dynamic Like "zlib", but the zlib library is expected to be a shared
# library and will be loaded in run-time by the OpenSSL library.
# sctp include SCTP support
# 386 generate 80386 code
# no-sse2 disables IA-32 SSE2 code, above option implies no-sse2
# no-<cipher> build without specified algorithm (rsa, idea, rc5, ...)
# -<xxx> +<xxx> compiler options are passed through
#
# DEBUG_SAFESTACK use type-safe stacks to enforce type-safety on stack items
# provided to stack calls. Generates unique stack functions for
# each possible stack type.
# BN_LLONG use the type 'long long' in crypto/bn/bn.h
# RC4_CHAR use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
# Following are set automatically by this script
#
# MD5_ASM use some extra md5 assember,
# SHA1_ASM use some extra sha1 assember, must define L_ENDIAN for x86
# RMD160_ASM use some extra ripemd160 assember,
# SHA256_ASM sha256_block is implemented in assembler
# SHA512_ASM sha512_block is implemented in assembler
# AES_ASM ASE_[en|de]crypt is implemented in assembler
