77 # meaningful), it triggers a number configuration options,

79 # argued that the only reason to produce statically linked
80 # binaries (and in context it means executables linked with
81 # -static flag, and not just executables linked with static
82 # libcrypto.a) is to eliminate dependency on specific run-time,
83 # a.k.a. libc version. The mentioned config options are meant
84 # to achieve just that. Unfortunately on Linux it's impossible
85 # to eliminate the dependency completely for openssl executable
86 # because of getaddrinfo and gethostbyname calls, which can
87 # invoke dynamically loadable library facility anyway to meet
88 # the lookup requests. For this reason on Linux statically
89 # linked openssl executable has rather debugging value than

2658 This module can be used in two modes, interactively and as a module containing
2659 all the data recorded by OpenSSL's Configure script.
2661 When used interactively, simply run it as any perl script, with at least one
2662 option, and you will get the information you ask for. See L</OPTIONS> below.
2664 When loaded as a module, you get a few databanks with useful information to
2665 perform build related tasks. The databanks are:
2667 %config Configured things.
2668 %target The OpenSSL config target with all inheritances
2670 %disabled The features that are disabled.
2671 @disablables The list of features that can be disabled.
2672 %withargs All data given through --with-THING options.
2673 %unified_info All information that was computed from the build.info
2682 Print a brief help message and exit.
2686 Print the manual page and exit.
2688 =item B<--dump> | B<-d>
2690 Print all relevant configuration data. This is equivalent to B<--command-line>
2691 B<--options> B<--target> B<--environment> B<--make-variables>
2692 B<--build-parameters>.
2694 =item B<--command-line> | B<-c>
2696 Print the current configuration command line.
2698 =item B<--options> | B<-o>
2700 Print the features, both enabled and disabled, and display defined macro and
2701 skipped directories where applicable.
2703 =item B<--target> | B<-t>
2705 Print the config attributes for this config target.
2707 =item B<--environment> | B<-e>
2709 Print the environment variables and their values at the time of configuration.
2711 =item B<--make-variables> | B<-m>
