2742
2743configdata.pm - configuration data for OpenSSL builds
2744
2745=head1 SYNOPSIS
2746
2747Interactive:
2748
2749 perl configdata.pm [options]
2750
2751As data bank module:
2752
2753 use configdata;
f2d4be3b 2754
b1fafff6
RL		 2755=head1 DESCRIPTION
2756
2757This module can be used in two modes, interactively and as a module containing
2758all the data recorded by OpenSSL's Configure script.
2759
2760When used interactively, simply run it as any perl script, with at least one
2761option, and you will get the information you ask for. See L</OPTIONS> below.
2762
2763When loaded as a module, you get a few databanks with useful information to
2764perform build related tasks. The databanks are:
2765
2766 %config Configured things.
2767 %target The OpenSSL config target with all inheritances
2768 resolved.
2769 %disabled The features that are disabled.
2770 @disablables The list of features that can be disabled.
2771 %withargs All data given through --with-THING options.
2772 %unified_info All information that was computed from the build.info
2773 files.
