84# to eliminate the dependency completely for openssl executable

2712
2713configdata.pm - configuration data for OpenSSL builds
2714
2715=head1 SYNOPSIS
2716
2717Interactive:
2718
2719 perl configdata.pm [options]
2720
2721As data bank module:
2722
2723 use configdata;
f2d4be3b 2724
b1fafff6
RL		 2725=head1 DESCRIPTION
2726
2727This module can be used in two modes, interactively and as a module containing
2728all the data recorded by OpenSSL's Configure script.
2729
2730When used interactively, simply run it as any perl script, with at least one
2731option, and you will get the information you ask for. See L</OPTIONS> below.
2732
2733When loaded as a module, you get a few databanks with useful information to
2734perform build related tasks. The databanks are:
2735
2736 %config Configured things.
2737 %target The OpenSSL config target with all inheritances
2738 resolved.
2739 %disabled The features that are disabled.
2740 @disablables The list of features that can be disabled.
2741 %withargs All data given through --with-THING options.
2742 %unified_info All information that was computed from the build.info
2743 files.
