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
87# the lookup requests. For this reason on Linux statically

2733
2734configdata.pm - configuration data for OpenSSL builds
2735
2736=head1 SYNOPSIS
2737
2738Interactive:
2739
2740 perl configdata.pm [options]
2741
2742As data bank module:
2743
2744 use configdata;
f2d4be3b 2745
b1fafff6
RL		 2746=head1 DESCRIPTION
2747
2748This module can be used in two modes, interactively and as a module containing
2749all the data recorded by OpenSSL's Configure script.
2750
2751When used interactively, simply run it as any perl script, with at least one
2752option, and you will get the information you ask for. See L</OPTIONS> below.
2753
2754When loaded as a module, you get a few databanks with useful information to
2755perform build related tasks. The databanks are:
2756
2757 %config Configured things.
2758 %target The OpenSSL config target with all inheritances
2759 resolved.
2760 %disabled The features that are disabled.
2761 @disablables The list of features that can be disabled.
2762 %withargs All data given through --with-THING options.
2763 %unified_info All information that was computed from the build.info
2764 files.
