Is there any alternative to removing package-depends.dot and 
especially pn-depends.dot? The reason I ask is because we use 
pn-dependes.dot when visualizing the dependencies between packages. 
Even though task-depends.dot is more complete, trying to render it 
is near impossible given the sheer number of nodes and edges it 
contains. Already visualizing pn-depends.dot is hard but possible 
with some gvpr and tred filtering. Here are some statistics from 
one of my typical builds:

                        Nodes  Edges
                        -----  ------
pn-depends.dot           1183   12087
package-depends.dot      5939   55615
task-depends.dot        13756  125870

As can be seen, the number of nodes and edges in task-depends.dot 
is a magnitude greater than in pn-depends.dot.
