86# to eliminate the dependency completely for openssl executable
87# because of getaddrinfo and gethostbyname calls, which can

2685
2686configdata.pm - configuration data for OpenSSL builds
2687
2688=head1 SYNOPSIS
2689
2690Interactive:
2691
2692 perl configdata.pm [options]
2693
2694As data bank module:
2695
2696 use configdata;
f2d4be3b 2697
b1fafff6
RL		 2698=head1 DESCRIPTION
2699
2700This module can be used in two modes, interactively and as a module containing
2701all the data recorded by OpenSSL's Configure script.
2702
2703When used interactively, simply run it as any perl script, with at least one
2704option, and you will get the information you ask for. See L</OPTIONS> below.
2705
2706When loaded as a module, you get a few databanks with useful information to
2707perform build related tasks. The databanks are:
2708
2709 %config Configured things.
2710 %target The OpenSSL config target with all inheritances
2711 resolved.
2712 %disabled The features that are disabled.
2713 @disablables The list of features that can be disabled.
2714 %withargs All data given through --with-THING options.
2715 %unified_info All information that was computed from the build.info
2716 files.
