[Lemon-user] Probléme d'execution d'un programme c++ utilisant Lemon library

Hi,

LEMON is capable of both reading and writing it, see this for example -
http://lemon.cs.elte.hu/pub/tutorial/a00018.html

We used to provide a fairly basic graph editor for the LGF format. I's
called glemon. Unfortunately it's been abandoned for many years. But you
may still try to build and use it.

Otherwise I'm not aware of any third party software that support LGF.

However it is designed to be as simple as possible, so is should be
straightforward to convert it to any other format.

Regards,
Alpár
