68 The constructor creates a new urpm object. It's a blessed hash that
69 contains fields from L<URPM>, and also the following fields:
70
71 B<source>: { id => src_rpm_file|spec_file }
72
73 B<media>: [ {
74 start => int, end => int, name => string, url => string,

77 iso => string, downloader => string,
78 ignore => bool, update => bool, modified => bool, really_modified => bool,
79 unknown_media_info => bool,
80 } ],
81
82 All C<URPM> methods are available on an urpm object.
