76# argued that the only reason to produce statically linked
77# binaries (and in context it means executables linked with
78# -static flag, and not just executables linked with static
79# libcrypto.a) is to eliminate dependency on specific run-time,
80# a.k.a. libc version. The mentioned config options are meant
81# to achieve just that. Unfortunately on Linux it's impossible
82# to eliminate the dependency completely for openssl executable
83# because of getaddrinfo and gethostbyname calls, which can
84# invoke dynamically loadable library facility anyway to meet
85# the lookup requests. For this reason on Linux statically
86# linked openssl executable has rather debugging value than
87# production quality.

2548configdata.pm - configuration data for OpenSSL builds
2549
2550=head1 SYNOPSIS
2551
2552Interactive:
2553
2554 perl configdata.pm [options]
2555
2556As data bank module:
2557
2558 use configdata;

RL		 2560=head1 DESCRIPTION
2561
2562This module can be used in two modes, interactively and as a module containing
2563all the data recorded by OpenSSL's Configure script.
2564
2565When used interactively, simply run it as any perl script, with at least one
2566option, and you will get the information you ask for. See L</OPTIONS> below.
2567
2568When loaded as a module, you get a few databanks with useful information to
2569perform build related tasks. The databanks are:
2570
2571 %config Configured things.
2572 %target The OpenSSL config target with all inheritances
2573 resolved.
2574 %disabled The features that are disabled.
2575 @disablables The list of features that can be disabled.
2576 %withargs All data given through --with-THING options.
2577 %unified_info All information that was computed from the build.info
2578 files.
