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

2746
2747configdata.pm - configuration data for OpenSSL builds
2748
2749=head1 SYNOPSIS
2750
2751Interactive:
2752
2753 perl configdata.pm [options]
2754
2755As data bank module:
2756
2757 use configdata;
f2d4be3b 2758
b1fafff6
RL		 2759=head1 DESCRIPTION
2760
2761This module can be used in two modes, interactively and as a module containing
2762all the data recorded by OpenSSL's Configure script.
2763
2764When used interactively, simply run it as any perl script, with at least one
2765option, and you will get the information you ask for. See L</OPTIONS> below.
2766
2767When loaded as a module, you get a few databanks with useful information to
2768perform build related tasks. The databanks are:
2769
2770 %config Configured things.
2771 %target The OpenSSL config target with all inheritances
2772 resolved.
2773 %disabled The features that are disabled.
2774 @disablables The list of features that can be disabled.
2775 %withargs All data given through --with-THING options.
2776 %unified_info All information that was computed from the build.info
2777 files.
