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

2653
2654configdata.pm - configuration data for OpenSSL builds
2655
2656=head1 SYNOPSIS
2657
2658Interactive:
2659
2660 perl configdata.pm [options]
2661
2662As data bank module:
2663
2664 use configdata;
f2d4be3b 2665
b1fafff6
RL		 2666=head1 DESCRIPTION
2667
2668This module can be used in two modes, interactively and as a module containing
2669all the data recorded by OpenSSL's Configure script.
2670
2671When used interactively, simply run it as any perl script, with at least one
2672option, and you will get the information you ask for. See L</OPTIONS> below.
2673
2674When loaded as a module, you get a few databanks with useful information to
2675perform build related tasks. The databanks are:
2676
2677 %config Configured things.
2678 %target The OpenSSL config target with all inheritances
2679 resolved.
2680 %disabled The features that are disabled.
2681 @disablables The list of features that can be disabled.
2682 %withargs All data given through --with-THING options.
2683 %unified_info All information that was computed from the build.info
2684 files.
