#               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)
34
#
35 36
# --cross-compile-prefix Add specified prefix to binutils components.

37 38 39
# --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.
#
40 41 42 43 44

# [no-]zlib     [don't] compile support for zlib compression.

It's to test out a new "unified" building system.

One cool feature is that you can have your build directory elsewhere,
for example:

    make clean          # Clean the current configuration away
    mkdir $plausible_builddir
    cd $plausible_builddir
    $plausible_to_sourcedir/config --unified
    make
    make test
