Reviewing my post above , in which I presented a code I found about adding support paths , I got the filling that I might get missunderstood . When I wrote "I , personally , added in the lisp file ...." , I didn't mean to overestimate myshelf . I just wanted to say that I simply had the idea of adding some lines and made my thought common , becouse it might interest others too . It's been many years since I spoke english very well , so please excuse me if sometimes I don't exprimate myshelf correctly .
