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

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.
