When I tried to use readgraph to read a graph from a file that geng had 
made, I got the error message "illegal char 'B' - use '.' to exit". When 
I tried several different formats with listg, readgraph complained in 
some cases about illegal edges and in some about illegal chars but never 
succeeded. How can I read a graph from a file? Please help me.
