This would be interesting, I can help testing the library, at least. I have
downloaded the ggl from the boost sandbox.

This puzzles me, because I pointed correctly my makefile, and even included
the -I option, but even then in some cases was not able to find the library
correctly. This is surely my mistake, I will fix it.

If there is any references, or if I can help, please contact me.

As before, help is welcome, in the form of testing the library, just using

I'm using now for my PhD thesis project, including it in a groundwater
simulation. As soon I have a little more time I will take a better look in
the code itself.
