82# libcrypto.a) is to eliminate dependency on specific run-time,

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

2587
2588configdata.pm - configuration data for OpenSSL builds
2589
2590=head1 SYNOPSIS
2591
2592Interactive:
2593
2594 perl configdata.pm [options]
2595
2596As data bank module:
2597
2598 use configdata;
f2d4be3b 2599
b1fafff6
RL		 2600=head1 DESCRIPTION
2601
2602This module can be used in two modes, interactively and as a module containing
2603all the data recorded by OpenSSL's Configure script.
2604
2605When used interactively, simply run it as any perl script, with at least one
2606option, and you will get the information you ask for. See L</OPTIONS> below.
2607
2608When loaded as a module, you get a few databanks with useful information to
2609perform build related tasks. The databanks are:
2610
2611 %config Configured things.
2612 %target The OpenSSL config target with all inheritances
2613 resolved.
2614 %disabled The features that are disabled.
2615 @disablables The list of features that can be disabled.
2616 %withargs All data given through --with-THING options.
2617 %unified_info All information that was computed from the build.info
2618 files.
