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

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

2712 all the data recorded by OpenSSL's Configure script.
2714 When used interactively, simply run it as any perl script, with at least one
2715 option, and you will get the information you ask for. See L</OPTIONS> below.
2717 When loaded as a module, you get a few databanks with useful information to
2718 perform build related tasks. The databanks are:
2720 %config Configured things.
2721 %target The OpenSSL config target with all inheritances
2723 %disabled The features that are disabled.
2724 @disablables The list of features that can be disabled.
2725 %withargs All data given through --with-THING options.
2726 %unified_info All information that was computed from the build.info
2735 Print a brief help message and exit.
2739 Print the manual page and exit.

2745 B<--build-parameters>.
2747 =item B<--command-line> | B<-c>

2751 =item B<--options> | B<-o>
2753 Print the features, both enabled and disabled, and display defined macro and
2754 skipped directories where applicable.
2756 =item B<--target> | B<-t>
2758 Print the config attributes for this config target.
2760 =item B<--environment> | B<-e>
2762 Print the environment variables and their values at the time of configuration.
2764 =item B<--make-variables> | B<-m>
2766 Print the main make variables generated in the current configuration
2768 =item B<--build-parameters> | B<-b>
2770 Print the build parameters, i.e. build file and build file templates.
