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

+=head1 NAME
+
+configdata.pm - configuration data for OpenSSL builds
+
+=head1 SYNOPSIS
+
+Interactive:
+
+ perl configdata.pm [options]
+
+As data bank module:
+
+ use configdata;
+
+=head1 DESCRIPTION
+
+This module can be used in two modes, interactively and as a module containing
+all the data recorded by OpenSSL's Configure script.
+
+When used interactively, simply run it as any perl script, with at least one
+option, and you will get the information you ask for. See L</OPTIONS> below.
+
+When loaded as a module, you get a few databanks with useful information to
+perform build related tasks. The databanks are:
+
+ %config Configured things.
+ %target The OpenSSL config target with all inheritances
+ resolved.
+ %disabled The features that are disabled.
+ @disablables The list of features that can be disabled.
+ %withargs All data given through --with-THING options.
+ %unified_info All information that was computed from the build.info
+ files.
+
+=head1 OPTIONS

+Print a brief help message and exit.
+
+=item B<--man>

+Print the config attributes for this config target.
+
+=item B<--environment> | B<-e>
+

+
+=item B<--make-variables> | B<-m>
+
+Print the main make variables generated in the current configuration
+
+=item B<--build-parameters> | B<-b>
+
+Print the build parameters, i.e. build file and build file templates.
+
