Comment (by ncohen):

 Yooooooo,

 > Sorry if I am not very active in these tickets, but I'm quite busy in
 these days...

 Okay okay. I write these tickets because I want to have some
 `Graph(filename)` constructor in order to not meet again this problem I
 had with your .nde files.

 > Just to say that when I inserted `igraph`, the variable `vertex_labels`
 was already there, and I only used it in my code. Indeed, you can find
 examples (written before igraph) where this variable was used (for
 instance, in `cliques_get_max_clique_graph`).

 In `cliques_get_max_clique_graph` it seems to be an argument of `.show()`
 (to display the labels) not an argument of `Graph.__init__`. In the
 constructor, the only occurrence of this `vertex_labels` argument is in
 the igraph code. If it is user anywhere else, well, it is actually
 ignored. It is not very bad anyway, just something that has to be done.
