86# to eliminate the dependency completely for openssl executable
87# because of getaddrinfo and gethostbyname calls, which can
88# invoke dynamically loadable library facility anyway to meet
89# the lookup requests. For this reason on Linux statically

2647
2648configdata.pm - configuration data for OpenSSL builds
2649
2650=head1 SYNOPSIS
2651
2652Interactive:
2653
2654 perl configdata.pm [options]
2655
2656As data bank module:
2657
2658 use configdata;
f2d4be3b 2659
b1fafff6
RL		 2660=head1 DESCRIPTION
2661
2662This module can be used in two modes, interactively and as a module containing
2663all the data recorded by OpenSSL's Configure script.
2664
2665When used interactively, simply run it as any perl script, with at least one
2666option, and you will get the information you ask for. See L</OPTIONS> below.
2667
2668When loaded as a module, you get a few databanks with useful information to
2669perform build related tasks. The databanks are:
2670
2671 %config Configured things.
2672 %target The OpenSSL config target with all inheritances
2673 resolved.
2674 %disabled The features that are disabled.
2675 @disablables The list of features that can be disabled.
2676 %withargs All data given through --with-THING options.
2677 %unified_info All information that was computed from the build.info
2678 files.
