+=head1 NAME
+
+FS::part_pkg_link - Object methods for part_pkg_link records
+
+=head1 SYNOPSIS
+
+  use FS::part_pkg_link;
+
+  $record = new FS::part_pkg_link \%hash;
+  $record = new FS::part_pkg_link { 'column' => 'value' };
+
+  $error = $record->insert;
+
+  $error = $new_record->replace($old_record);
+
+  $error = $record->delete;
+
+  $error = $record->check;
+
+=head1 DESCRIPTION
+
+An FS::part_pkg_link object represents an link from one package definition to
+another.  FS::part_pkg_link inherits from FS::Record.  The following fields are
+currently supported:
+
+=over 4
+
+=item pkglinknum
+
+primary key
+
+=item src_pkgpart
+
+Source package (see L<FS::part_pkg>)
+
+=item dst_pkgpart
+
+Destination package (see L<FS::part_pkg>)
+
+=item link_type
+
+Link type - currently, "bill" (source package bills a line item from target
+package), or "svc" (source package includes services from target package).
+
+=back
+
+=head1 METHODS
+
+=over 4
+
+=item new HASHREF
+
+Creates a new link.  To add the link to the database, see L<"insert">.
+
+Note that this stores the hash reference, not a distinct copy of the hash it
+points to.  You can ask the object for a copy with the I<hash> method.
+
+=cut
+
+# the new method can be inherited from FS::Record, if a table method is defined
+
+sub table { 'part_pkg_link'; }
+
+=item insert
+
+Adds this record to the database.  If there is an error, returns the error,
+otherwise returns false.
+
+=cut
+
+# the insert method can be inherited from FS::Record
+
+=item delete
+
+Delete this record from the database.
+
+=cut
+
+# the delete method can be inherited from FS::Record
+
+=item replace OLD_RECORD
+
+Replaces the OLD_RECORD with this one in the database.  If there is an error,
+returns the error, otherwise returns false.
+
+=cut
+
+# the replace method can be inherited from FS::Record
+
+=item check
+
+Checks all fields to make sure this is a valid link.  If there is
+an error, returns the error, otherwise returns false.  Called by the insert
+and replace methods.
+
+=cut
+
+# the check method should currently be supplied - FS::Record contains some
+# data checking routines
+
+sub check {
+  my $self = shift;
+
+  my $error = 
+    $self->ut_numbern('pkglinknum')
+    || $self->ut_foreign_key('src_pkgpart', 'part_pkg', 'pkgpart')
+    || $self->ut_foreign_key('dst_pkgpart', 'part_pkg', 'pkgpart')
+    || $self->ut_text('link_type', [ 'bill', 'svc' ] )
+  ;
+  return $error if $error;
+
+  $self->SUPER::check;
+}
+
+=item src_pkg
+
+Returns the source part_pkg object (see L<FS::part_pkg>).
+
+=cut
+
+sub src_pkg {
+  my $self = shift;
+  qsearchs('part_pkg', { 'pkgpart' => $self->src_pkgpart } );
+}
+
+=item dst_pkg
+
+Returns the source part_pkg object (see L<FS::part_pkg>).
+
+=cut
+
+sub dst_pkg {
