[GRASS5] dig_plus file - How does it work?

[Flavio]

Hi all,

On my eternal quest to find out how the dig_plus file is contructed, I have 
only found the following reference on the programmer's manual: 

" Vector Index and Pointer File:..For this reason, and since the internal structure of the dig_plus file is 
complex, the format of this file will not be described. "

so, I am still looking for someone how might know where I can get more 
detailed information about this file. 
Any information will be greatly appriciated. 

thanks.
