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

2764
2765configdata.pm - configuration data for OpenSSL builds
2766
2767=head1 SYNOPSIS
2768
2769Interactive:
2770
2771 perl configdata.pm [options]
2772
2773As data bank module:
2774
2775 use configdata;
f2d4be3b 2776
b1fafff6
RL		 2777=head1 DESCRIPTION
2778
2779This module can be used in two modes, interactively and as a module containing
2780all the data recorded by OpenSSL's Configure script.
2781
2782When used interactively, simply run it as any perl script, with at least one
2783option, and you will get the information you ask for. See L</OPTIONS> below.
2784
2785When loaded as a module, you get a few databanks with useful information to
2786perform build related tasks. The databanks are:
2787
2788 %config Configured things.
2789 %target The OpenSSL config target with all inheritances
2790 resolved.
2791 %disabled The features that are disabled.
2792 @disablables The list of features that can be disabled.
2793 %withargs All data given through --with-THING options.
2794 %unified_info All information that was computed from the build.info
2795 files.
