394=head1 NAME
395
396configdata.pm - configuration data for OpenSSL builds
397
398=head1 SYNOPSIS
399
400Interactive:
401
402 perl configdata.pm [options]
403
404As data bank module:
405
406 use configdata;
407
408=head1 DESCRIPTION
409
410This module can be used in two modes, interactively and as a module containing
411all the data recorded by OpenSSL's Configure script.
412
413When used interactively, simply run it as any perl script.
414If run with no arguments, it will rebuild the build file (Makefile or
415corresponding).
416With at least one option, it will instead get the information you ask for, or
417re-run the configuration process.
418See L</OPTIONS> below for more information.
419
420When loaded as a module, you get a few databanks with useful information to
421perform build related tasks. The databanks are:
422
423 %config Configured things.
424 %target The OpenSSL config target with all inheritances
425 resolved.
426 %disabled The features that are disabled.
427 @disablables The list of features that can be disabled.
428 %withargs All data given through --with-THING options.
429 %unified_info All information that was computed from the build.info
430 files.
431
432=head1 OPTIONS
433
434=over 4

441
442Print the manual page and exit.
443
444=item B<--dump> | B<-d>

451
452Print the current configuration command line.
453
454=item B<--options> | B<-o>
455
456Print the features, both enabled and disabled, and display defined macro and
457skipped directories where applicable.
458
459=item B<--target> | B<-t>
460
461Print the config attributes for this config target.
462
463=item B<--environment> | B<-e>
464
465Print the environment variables and their values at the time of configuration.
466
467=item B<--make-variables> | B<-m>
468
469Print the main make variables generated in the current configuration
470
471=item B<--build-parameters> | B<-b>
472
473Print the build parameters, i.e. build file and build file templates.
474

476
477Re-run the configuration process.
478
