 use Lintian::Lab::Manifest;
 
 my $olist = Lintian::Lab::Manifest->new ('binary');
 my $nlist = Lintian::Lab::Manifest->new ('binary');
 $olist->read_list ('old/binary-packages');
 $nlist->read_list ('new/binary-packages');

 foreach my $added (@{ $diff->added }) {
    my $entry = $nlist->get (@$added);
    # do something
 }
 foreach my $removed (@{ $diff->removed }) {
    my $entry = $olist->get (@$removed);
    # do something
 }
 foreach my $changed (@{ $diff->changed }) {

DESCRIPTION

Instances of this class provides access to the packages list used by the Lab as caches.  

METHODS

$diff->added

Returns a listref containing the keys of the elements that has been added.

Each element is a listref of keys; this list (when dereferenced) can be used with the manifest's get method to look up the item.

$diff->removed

Returns a listref containing the keys of the elements that has been removed.

Each element is a listref of keys; this list (when dereferenced) can be used with the manifest's get method to look up the item.

$diff->changed

Returns a listref containing the keys of the elements that has been changed.

Each element is a listref of keys; this list (when dereferenced) can be used with the manifest's get method to look up the item.

$diff->nlist

Returns the ``new'' manifest used to create this diff. Note the manifest is not copied and may have been changed since the diff has been created.

$diff->olist

Returns the ``orig'' manifest used to create this diff. Note the manifest is not copied and may have been changed since the diff has been created.
