-=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
-
-=over 4
-
-=item B<--help>
-
-Print a brief help message and exit.
-
-=item B<--man>
-
-Print the manual page and exit.
-
-=item B<--dump> | B<-d>
-
-Print all relevant configuration data. This is equivalent to B<--command-line>
-B<--options> B<--target> B<--environment> B<--make-variables>
-B<--build-parameters>.
-
-=item B<--command-line> | B<-c>
-
-Print the current configuration command line.
-
-=item B<--options> | B<-o>
-
-Print the features, both enabled and disabled, and display defined macro and
-skipped directories where applicable.
-
-=item B<--target> | B<-t>
-
-Print the config attributes for this config target.
-
-=item B<--environment> | B<-e>
-
-Print the environment variables and their values at the time of configuration.
-
-=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.
-
-=item B<--reconfigure> | B<--reconf> | B<-r>
-
-Redo the configuration.
-
-=item B<--verbose> | B<-v>
-
-Verbose output.
