[GRASS5] Training sites and classification

[Gualter Barbas Baptista]

How can I define the training sites in GRASS? I tried using i.class but 
I'm not very clear on how to deal with it.
In fact I'm a bit confused about the classification processes in GRASS, 
as the documentation is not very clear to me. Can anyone give some hints 
on this?

Thanks,
