Código simples, com algumas funções e que visa tornar ainda mais fácil a configuração do wpa_supplicant.

Este programa lê alguns dados fornecidos pelo usuário como ssid/usuário/login/interface etc.

Escreve alguns arquivos e faz a conexão com base nestes dados; obtendo o endereço por dhcp.

Suporte para as encriptações Open, WEP e WPA/WPA2.
