Hi again,

one last comment on this:

Beyond the CRLF problem, I found that the result, returned by tsort on
the file with dos line endings had duplicates. So it is totally
incorrect.

Than I've tried the followling:

Instead of giving this as an input:
15731102 16019755
15731102 15731104
15731102 15731101
15731102 15731105
15731102 15731103
15731101
15731102

I gave tsort this one:
15731102 16019755
15731102 15731104
15731102 15731101
15731102 15731105
15731102 15731103
15731101 15731101
15731102 15731102

and it works like a charm.

So the problem is only with the format of the single nodes without
dependent ones.

Have a nice day!

Ivan Ivanov
