2693
2694configdata.pm - configuration data for OpenSSL builds
2695
2696=head1 SYNOPSIS
2697
2698Interactive:
2699
2700 perl configdata.pm [options]
2701
2702As data bank module:
2703
2704 use configdata;
f2d4be3b 2705
b1fafff6
RL		 2706=head1 DESCRIPTION
2707
2708This module can be used in two modes, interactively and as a module containing
2709all the data recorded by OpenSSL's Configure script.
2710
2711When used interactively, simply run it as any perl script, with at least one
2712option, and you will get the information you ask for. See L</OPTIONS> below.
2713
2714When loaded as a module, you get a few databanks with useful information to
2715perform build related tasks. The databanks are:
2716
2717 %config Configured things.
2718 %target The OpenSSL config target with all inheritances
2719 resolved.
2720 %disabled The features that are disabled.
2721 @disablables The list of features that can be disabled.
2722 %withargs All data given through --with-THING options.
2723 %unified_info All information that was computed from the build.info
2724 files.
