[pgf-tikz] Creating directed graphs with edge labels

[Henri Menke]

No, there are no such plan.  I don't have the time and more importantly
not the expertise to implement this.  The graphdrawing library was
implemented by Till and his students.  Unless he picks it up again, it's
unlikely that someone else will.

Cheers, Henri
