74 # with a '-' or '+' are recognized, as well as Windows-style
75 # options beginning with a '/'. If the option contains arguments
76 # separated by spaces, then the URL-style notation %20 can be
77 # used for the space character in order to avoid having to quote
78 # the option. For example, -opt%20arg gets expanded to -opt arg.
79 # In fact, any ASCII character can be encoded as %xx using its
80 # hexadecimal encoding.
81 # -static while -static is also a pass-through compiler option (and
82 # as such is limited to environments where it's actually
83 # meaningful), it triggers a number configuration options,
84 # namely no-pic, no-shared and no-threads. It is
85 # argued that the only reason to produce statically linked
86 # binaries (and in context it means executables linked with
87 # -static flag, and not just executables linked with static
88 # libcrypto.a) is to eliminate dependency on specific run-time,
89 # a.k.a. libc version. The mentioned config options are meant
90 # to achieve just that. Unfortunately on Linux it's impossible
91 # to eliminate the dependency completely for openssl executable
92 # because of getaddrinfo and gethostbyname calls, which can
93 # invoke dynamically loadable library facility anyway to meet
94 # the lookup requests. For this reason on Linux statically
95 # linked openssl executable has rather debugging value than
98 # BN_LLONG use the type 'long long' in crypto/bn/bn.h
99 # RC4_CHAR use 'char' instead of 'int' for RC4_INT in crypto/rc4/rc4.h

2696 When used interactively, simply run it as any perl script, with at least one
2697 option, and you will get the information you ask for. See L</OPTIONS> below.
2699 When loaded as a module, you get a few databanks with useful information to
2700 perform build related tasks. The databanks are:
2702 %config Configured things.
2703 %target The OpenSSL config target with all inheritances
2705 %disabled The features that are disabled.
2706 @disablables The list of features that can be disabled.
2707 %withargs All data given through --with-THING options.
2708 %unified_info All information that was computed from the build.info
2717 Print a brief help message and exit.

2729 =item B<--command-line> | B<-c>

2744 Print the environment variables and their values at the time of configuration.
2746 =item B<--make-variables> | B<-m>
2748 Print the main make variables generated in the current configuration
2750 =item B<--build-parameters> | B<-b>
2752 Print the build parameters, i.e. build file and build file templates.
