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

2759 This module can be used in two modes, interactively and as a module containing
2760 all the data recorded by OpenSSL's Configure script.
2762 When used interactively, simply run it as any perl script, with at least one
2763 option, and you will get the information you ask for. See L</OPTIONS> below.
2765 When loaded as a module, you get a few databanks with useful information to
2766 perform build related tasks. The databanks are:
2768 %config Configured things.
2769 %target The OpenSSL config target with all inheritances
2771 %disabled The features that are disabled.
2772 @disablables The list of features that can be disabled.
2773 %withargs All data given through --with-THING options.
2774 %unified_info All information that was computed from the build.info
2783 Print a brief help message and exit.
