83# libcrypto.a) is to eliminate dependency on specific run-time,

85# to achieve just that. Unfortunately on Linux it's impossible
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
90# linked openssl executable has rather debugging value than

2760
2761configdata.pm - configuration data for OpenSSL builds
2762
2763=head1 SYNOPSIS
2764
2765Interactive:
2766
2767 perl configdata.pm [options]
2768
2769As data bank module:
2770
2771 use configdata;
f2d4be3b 2772
b1fafff6
RL		 2773=head1 DESCRIPTION
2774
2775This module can be used in two modes, interactively and as a module containing
2776all the data recorded by OpenSSL's Configure script.
2777
2778When used interactively, simply run it as any perl script, with at least one
2779option, and you will get the information you ask for. See L</OPTIONS> below.
2780
2781When loaded as a module, you get a few databanks with useful information to
2782perform build related tasks. The databanks are:
2783
2784 %config Configured things.
2785 %target The OpenSSL config target with all inheritances
2786 resolved.
2787 %disabled The features that are disabled.
2788 @disablables The list of features that can be disabled.
2789 %withargs All data given through --with-THING options.
2790 %unified_info All information that was computed from the build.info
2791 files.
