 length of wires then you might be looking for a <b>minimum spanning
 tree</b> in an undirected graph. This can be found using the Kruskal
-algorithm: the function \ref lemon::kruskal "LEMON Kruskal " does
-this job for you.  After we had a graph \c g and a cost map \c
-edge_cost_map , the following code fragment shows an example how to get weight of the minmum spanning tree (in this first example the costs are uniform; this is of course not the case in real life applications):
+algorithm: the function \ref lemon::kruskal "LEMON Kruskal " does this
+job for you.  
+
+First make a graph \c g and a cost map \c
+edge_cost_map, then make a bool edgemap \c tree_map or a vector \c
+tree_edge_vec for the algorithm output. After calling the function it
+gives back the weight of the minimum spanning tree and the \c tree_map or
+the \c tree_edge_vec contains the edges of the tree.
+
+If you want to store the edges in a bool edgemap, then use the
+function as follows:
 
 \dontinclude kruskal_demo.cc
-\skip std::cout 
-\until kruskal
-
-In the variable \c tree_map the function gives back an edge bool map, which contains the edges of the found tree.
-
-If the costs are non-uniform, for example  the cost is given by \c
-edge_cost_map_2 , or the edges of the tree  have to be given in a
-vector, then we can give to the kruskal a vector \c tree_edge_vec , instead of
-an edge bool map:
-
-\skip edge_cost_map_2 
-\until edge_cost_map_2, std::back_inserter
-
-And finally the next fragment shows how to use the functions \c makeKruskalMapInput and \c makeKruskalSequenceOutPut:
-
-\skip makeKruskalSequenceOutput
-\until tree_edge_vec
+\skip Kruskal with boolmap; 
+\until  std::endl
+
+And if you rather use a vector instead of a bool map:
+
+\skip Kruskal with vector; 
+\until std::endl
 
 See the whole program in \ref kruskal_demo.cc.
