84# to eliminate the dependency completely for openssl executable
85# because of getaddrinfo and gethostbyname calls, which can
86# invoke dynamically loadable library facility anyway to meet

2702
2703configdata.pm - configuration data for OpenSSL builds
2704
2705=head1 SYNOPSIS
2706
2707Interactive:
2708
2709 perl configdata.pm [options]
2710
2711As data bank module:
2712
2713 use configdata;
f2d4be3b 2714
b1fafff6
RL		 2715=head1 DESCRIPTION
2716
2717This module can be used in two modes, interactively and as a module containing
2718all the data recorded by OpenSSL's Configure script.
2719
2720When used interactively, simply run it as any perl script, with at least one
2721option, and you will get the information you ask for. See L</OPTIONS> below.
2722
2723When loaded as a module, you get a few databanks with useful information to
2724perform build related tasks. The databanks are:
2725
2726 %config Configured things.
2727 %target The OpenSSL config target with all inheritances
2728 resolved.
2729 %disabled The features that are disabled.
2730 @disablables The list of features that can be disabled.
2731 %withargs All data given through --with-THING options.
2732 %unified_info All information that was computed from the build.info
2733 files.
