[libredwg] Autocad 2010 (and prior) file format especification

[Jose Miguel Macanás]

I've read on the wiky of the project that  you don't have documentation 
on AutoCAD 2010 file especification:


http://www.opendesign.com/files/guestdownloads/OpenDesign_Specification_for_.dwg_files.pdf

Found here:

And other resources:

I hope this would be new information and helpful for the project.
