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

2547configdata.pm - configuration data for OpenSSL builds
2548
2549=head1 SYNOPSIS
2550
2551Interactive:
2552
2553 perl configdata.pm [options]
2554
2555As data bank module:
2556
2557 use configdata;

RL		 2559=head1 DESCRIPTION
2560
2561This module can be used in two modes, interactively and as a module containing
2562all the data recorded by OpenSSL's Configure script.
2563
2564When used interactively, simply run it as any perl script, with at least one
2565option, and you will get the information you ask for. See L</OPTIONS> below.
2566
2567When loaded as a module, you get a few databanks with useful information to
2568perform build related tasks. The databanks are:
2569
2570 %config Configured things.
2571 %target The OpenSSL config target with all inheritances
2572 resolved.
2573 %disabled The features that are disabled.
2574 @disablables The list of features that can be disabled.
2575 %withargs All data given through --with-THING options.
2576 %unified_info All information that was computed from the build.info
2577 files.
