86# to eliminate the dependency completely for openssl executable
87# because of getaddrinfo and gethostbyname calls, which can
88# invoke dynamically loadable library facility anyway to meet
89# the lookup requests. For this reason on Linux statically

2767
2768configdata.pm - configuration data for OpenSSL builds
2769
2770=head1 SYNOPSIS
2771
2772Interactive:
2773
2774 perl configdata.pm [options]
2775
2776As data bank module:
2777
2778 use configdata;
f2d4be3b 2779
b1fafff6
RL		 2780=head1 DESCRIPTION
2781
2782This module can be used in two modes, interactively and as a module containing
2783all the data recorded by OpenSSL's Configure script.
2784
2785When used interactively, simply run it as any perl script, with at least one
2786option, and you will get the information you ask for. See L</OPTIONS> below.
2787
2788When loaded as a module, you get a few databanks with useful information to
2789perform build related tasks. The databanks are:
2790
2791 %config Configured things.
2792 %target The OpenSSL config target with all inheritances
2793 resolved.
2794 %disabled The features that are disabled.
2795 @disablables The list of features that can be disabled.
2796 %withargs All data given through --with-THING options.
2797 %unified_info All information that was computed from the build.info
2798 files.
