[texhax] HELP - packages

[Lilian Teixeira]

Hi,
I am sorry if seem so stupid, but I used Latex only once and I can not
remember how to get those packages, such as:
\usepackage{a4wide}
\usepackage[latin1]{inputenc}
\usepackage[numbers]{natbib}
\usepackage[portuges]{babel}

I am totally lost.

Thanks for your help.

Lilian.
