2727
2728configdata.pm - configuration data for OpenSSL builds
2729
2730=head1 SYNOPSIS
2731
2732Interactive:
2733
2734 perl configdata.pm [options]
2735
2736As data bank module:
2737
2738 use configdata;
f2d4be3b 2739
b1fafff6
RL		 2740=head1 DESCRIPTION
2741
2742This module can be used in two modes, interactively and as a module containing
2743all the data recorded by OpenSSL's Configure script.
2744
2745When used interactively, simply run it as any perl script, with at least one
2746option, and you will get the information you ask for. See L</OPTIONS> below.
2747
2748When loaded as a module, you get a few databanks with useful information to
2749perform build related tasks. The databanks are:
2750
2751 %config Configured things.
2752 %target The OpenSSL config target with all inheritances
2753 resolved.
2754 %disabled The features that are disabled.
2755 @disablables The list of features that can be disabled.
2756 %withargs All data given through --with-THING options.
2757 %unified_info All information that was computed from the build.info
2758 files.
