igraph and usage of Read(klass, f, format=None, *args, **kwds) question

[ishwar.rattan at gmail.com]

I have a file with with adjacency list of an undirected graph one vertex list per input line [0 1, 1 2 3, 2 1, 3 1] assume a newline for commas (file is named adjl.txt). Can some one give an example of loading this into graph of 4 vertices?

import igraph
g = igraph.Graph()
g.Read("adjl.txt", "edgelist")
   does not work..

Help will be appreciated.
