quite honestly i’ve never seen a software documented like this one and it’s all built in.
i mean it’s dr.Stallmans’ baby for sure (1 milion lines of code - more or less ?) not all of it written by his hands but a good portion none-the-less.
the other learning materials are also very good but a little old. now just get this piece of software to be learned in schools around the world and we’d be set …
are some of the best i know so far … if anyone has anything better paid or otherwise let us know please …
