+=head1 NAME
+
+Bio::Map::OrderedPosition - Abstracts the notion of a member
+	of an ordered list of markers. Each marker is a certain distance
+	from the one in the ordered list before it.
+
+=head1 SYNOPSIS
+
+    use Bio::Map::OrderedPosition;
+	# the first marker in the sequence
+    my $position = new Bio::Map::OrderedPosition(-order => 1,
+			-positions => [ [ $map, 22.3] ] );
+	# the second marker in the sequence, 15.6 units from the fist one
+    my $position2 = new Bio::Map::OrderedPosition(-order => 2,
+			-positions => [ [ $map, 37.9] ] );
+	# the third marker in the sequence, coincidental with the second
+	# marker
+    my $position3 = new Bio::Map::OrderedPosition(-order => 3,
+                        -posititions => [ [ $map, 37.9]] );
+
+=head1 DESCRIPTION
+
+This object is an implementation of the PositionI interface and the
+Position object handles the specific values of a position.
+OrderedPosition is intended to be slightly more specific then Position
+but only specific enough for a parser from the MarkerIO subsystem to
+create and then pass to a client application to bless into the proper
+type. For an example of how this is intended to work, see the
+Mapmaker.pm.
+
+No units are assumed here - units are handled by context of which Map
+a position is placed in.
+
+Se Bio::Map::Position for additional information.

+
+ Title   : add_position_value
