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

2639
2640configdata.pm - configuration data for OpenSSL builds
2641
2642=head1 SYNOPSIS
2643
2644Interactive:
2645
2646 perl configdata.pm [options]
2647
2648As data bank module:
2649
2650 use configdata;
f2d4be3b 2651
b1fafff6
RL		 2652=head1 DESCRIPTION
2653
2654This module can be used in two modes, interactively and as a module containing
2655all the data recorded by OpenSSL's Configure script.
2656
2657When used interactively, simply run it as any perl script, with at least one
2658option, and you will get the information you ask for. See L</OPTIONS> below.
2659
2660When loaded as a module, you get a few databanks with useful information to
2661perform build related tasks. The databanks are:
2662
2663 %config Configured things.
2664 %target The OpenSSL config target with all inheritances
2665 resolved.
2666 %disabled The features that are disabled.
2667 @disablables The list of features that can be disabled.
2668 %withargs All data given through --with-THING options.
2669 %unified_info All information that was computed from the build.info
2670 files.
