Fwd: Development of precompiled shared libraries

[Ramón García]

I apologize for the delay in my answer.

This is a personal project with no academic purpose.

In my opinion I am prepared to perform this project. I have been
looking at the representation of objects for some time. But I am open
to any suggestions about smaller projects.

Best regards,

Ramon
