460
461 urpm - Mageia perl tools to handle the urpmi database
462
463 =head1 DESCRIPTION
464
465 C<urpm> is used by urpmi executables to manipulate packages and media
466 on a Mageia Linux distribution.
467
468 =head2 The urpm class
469
470 =over 4
471
472 =item urpm->new()
473
474 The constructor creates a new urpm object. It's a blessed hash that
475 contains fields from C<URPM>, and also the following fields:
476
477 B<source>: { id => src_rpm_file|spec_file }
478
479 B<media>: [ {
480 start => int, end => int, name => string, url => string,
481 virtual => bool, media_info_dir => string, with_synthesis => string,
482 no-media-info => bool,
483 iso => string, downloader => string,
484 ignore => bool, update => bool, modified => bool, really_modified => bool,
485 unknown_media_info => bool,
486 } ],
487
488 =back
489
490 =head1 SEE ALSO
491
492 The C<URPM> package is used to manipulate at a lower level synthesis and rpm
493 files.
