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

2805 perform build related tasks. The databanks are:

2808 %target The OpenSSL config target with all inheritances
2810 %disabled The features that are disabled.
2811 @disablables The list of features that can be disabled.
2812 %withargs All data given through --with-THING options.
2813 %unified_info All information that was computed from the build.info
2822 Print a brief help message and exit.
2826 Print the manual page and exit.
2828 =item B<--dump> | B<-d>

2831 B<--options> B<--target> B<--environment> B<--make-variables>
2832 B<--build-parameters>.
2834 =item B<--command-line> | B<-c>
2836 Print the current configuration command line.
2838 =item B<--options> | B<-o>
2840 Print the features, both enabled and disabled, and display defined macro and
2841 skipped directories where applicable.
2843 =item B<--target> | B<-t>
2845 Print the config attributes for this config target.
2847 =item B<--environment> | B<-e>
2849 Print the environment variables and their values at the time of configuration.
2851 =item B<--make-variables> | B<-m>
2853 Print the main make variables generated in the current configuration
2855 =item B<--build-parameters> | B<-b>
2857 Print the build parameters, i.e. build file and build file templates.
2859 =item B<--reconfigure> | B<--reconf> | B<-r>
