2696
2697configdata.pm - configuration data for OpenSSL builds
2698
2699=head1 SYNOPSIS
2700
2701Interactive:
2702
2703 perl configdata.pm [options]
2704
2705As data bank module:
2706
2707 use configdata;
f2d4be3b 2708
b1fafff6
RL		 2709=head1 DESCRIPTION
2710
2711This module can be used in two modes, interactively and as a module containing
2712all the data recorded by OpenSSL's Configure script.
2713
2714When used interactively, simply run it as any perl script, with at least one
2715option, and you will get the information you ask for. See L</OPTIONS> below.
2716
2717When loaded as a module, you get a few databanks with useful information to
2718perform build related tasks. The databanks are:
2719
2720 %config Configured things.
2721 %target The OpenSSL config target with all inheritances
2722 resolved.
2723 %disabled The features that are disabled.
2724 @disablables The list of features that can be disabled.
2725 %withargs All data given through --with-THING options.
2726 %unified_info All information that was computed from the build.info
2727 files.
