ALPM::DB - ALPM database class.

  ... load ALPM with options first ...

  my $localdb = ALPM->localdb;
  my $name    = $localdb->name;
  my $perl    = $localdb->find('perl');

  my $url       = 'ftp://ftp.archlinux.org/community/os/i686';
  my $syncdb    = ALPM->register_db( 'community' => $url );

  for my $pkg ( $syncdb->search( 'perl' ) ) {
      printf "%s %s\n", $pkg->name, $pkg->version;
  }

  for my $pkg ( $syncdb->find_group('xfce4')->pkgs ) {
      print join( q{ }, $pkg->attribs('name', 'version') ), "\n";
  }

  my @cache = $syncdb->pkgs;

  Usage   : my $name = $db->name;
  Returns : The name of the repository database.
            Ex: core, extra, community, etc...

  Usage   : my $url = $db->url;
  Returns : The url of the repository, the same one the DB
            was initialized with or the empty string if this
            is a 'local' database.
  Note    : This only returns one of the URL's of the repository.

  Usage   : my $package = $db->find( $package_name )
  Params  : $package_name - Exact name of the package to retrieve.
  Returns : An ALPM::Package object if the package is found.
            undef if the package with that name is not found.

  Usage   : my $group = $db->find_group( $group_name );
  Returns : An ALPM::Group object if it is found or undef.
            ALPM::Group objects have two accessors:
            $group->name - the name of the group
            $group->pkgs - A list of package objects in the group

  Usage   : my @results = $db->search( 'foo', 'bar', 'baz' );
  Params  : A list of strings to search for.
  Returns : An array of package objects whose name matched the search.

  Usage   : my @pkgs = $db->pkgs;
  Params  : None
  Returns : An array of all packages in the DB.

  Usage   : my @groups = $db->groups;
  Returns : An array of all groups in the DB.

  Usage    : $db->add_url( 'ftp://ftp.archlinux.org/extra/os/i686' );
  Purpose  : This adds a mirror for the repository.
  Params   : The URL for the root of the remote repository.

  Usage    : $db->set_pkg_reason( 'perl', 'explicit' );
  Params   : The package name and a new package reason.
             Reason can be 'explicit', 'implicit', 0, or 1.
  Purpose  : Changes the reason for installing the given package.
  Comments : Probably best to use on local database ...
  Returns  : Nothing.

  Usage   : $db->update;
  Params  : If provided a parameter, the update is forced.
  Purpose : Updates the local copy of the database's package list.
  Comment : This needs to create a transaction to work, so make sure
            you don't have any active transactions.

            Things may work incorrectly if the database is not updated.
            If there is no local db copy, the package cache will be empty.
  Returns : 1
  TODO    : Provide different return values like alpm does.
