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.

2576
2577configdata.pm - configuration data for OpenSSL builds
2578
2579=head1 SYNOPSIS
2580
2581Interactive:
2582
2583 perl configdata.pm [options]
2584
2585As data bank module:
2586
2587 use configdata;
f2d4be3b 2588
b1fafff6
RL		 2589=head1 DESCRIPTION
2590
2591This module can be used in two modes, interactively and as a module containing
2592all the data recorded by OpenSSL's Configure script.
2593
2594When used interactively, simply run it as any perl script, with at least one
2595option, and you will get the information you ask for. See L</OPTIONS> below.
2596
2597When loaded as a module, you get a few databanks with useful information to
2598perform build related tasks. The databanks are:
2599
2600 %config Configured things.
2601 %target The OpenSSL config target with all inheritances
2602 resolved.
2603 %disabled The features that are disabled.
2604 @disablables The list of features that can be disabled.
2605 %withargs All data given through --with-THING options.
2606 %unified_info All information that was computed from the build.info
2607 files.
