+#!/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:address@hidden:port
+#   socks4://username:address@hidden:port
+#   socks5://username:address@hidden: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
