[Boost-users] Bug in graph Example Code

Problem with the Kevin Bacon example:

    char_delimiters_separator < char >sep(false, "", ";");

should be

    char_delimiters_separator < char >sep(false, "", "|");

At least this is true with the dat file I have.

My output was:
William Shatner|Loaded Weapon 1 (1993)|Denise Richards has a Bacon 
number of 0
 has a Bacon number of 1
Denise Richards|Wild Things (1998)|Kevin Bacon has a Bacon number of 2
Patrick Stewart|Prince of Egypt, The (1998)|Steve Martin has a Bacon 
number of 2
Steve Martin|Novocaine (2000)|Kevin Bacon has a Bacon number of 2
...

It is now:
William Shatner has a Bacon number of 2
Denise Richards has a Bacon number of 1
Kevin Bacon has a Bacon number of 0
Patrick Stewart has a Bacon number of 2
Steve Martin has a Bacon number of 1
...

Another problem, it still does not produce the output described in the 
docs such as:

William Shatner was in Loaded Weapon 1 (1993) with Denise Richards
Denise Richards was in Wild Things (1998) with Kevin Bacon
Patrick Stewart was in Prince of Egypt, The (1998) with Steve Martin
...

Thanks,
