#!/bin/bash
# Script that executes wget using a socks proxy if the environment variable
# socks_proxy is set.
#
# The socks_proxy variable shall have one of the forms:
# socks://username:password@host:port
# socks4://username:password@host:port
# socks5://username:password@host:port
# with username, password and port fields being optional
#
# As socksification applies to the whole process, domains defined in the
# no_proxy setting are *not* excluded.
#
# Requisites: bash (version 3.2.3 or later), tsocks and wget
