+=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.
+
