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

2649
2650configdata.pm - configuration data for OpenSSL builds
2651
2652=head1 SYNOPSIS
2653
2654Interactive:
2655
2656 perl configdata.pm [options]
2657
2658As data bank module:
2659
2660 use configdata;
f2d4be3b 2661
b1fafff6
RL		 2662=head1 DESCRIPTION
2663
2664This module can be used in two modes, interactively and as a module containing
2665all the data recorded by OpenSSL's Configure script.
2666
2667When used interactively, simply run it as any perl script, with at least one
2668option, and you will get the information you ask for. See L</OPTIONS> below.
2669
2670When loaded as a module, you get a few databanks with useful information to
2671perform build related tasks. The databanks are:
2672
2673 %config Configured things.
2674 %target The OpenSSL config target with all inheritances
2675 resolved.
2676 %disabled The features that are disabled.
2677 @disablables The list of features that can be disabled.
2678 %withargs All data given through --with-THING options.
2679 %unified_info All information that was computed from the build.info
2680 files.
