Hello,

could you tell me where I can find the implementation of << for 
Triangulation_data_structure_3?
The number of empty line matches exactly one of the numbers written in the 
file (maybe the nuber of edges of facets, I don't know).
Surprisingly, all seem to work fine in binary mode (reading and writing).
In ascii mode, I cannot read what was written by <<.

Best,

Cédric
