# Script: Internet Speed (Ispeed)
# Author: Tiago Oliveira Weber

# Description: This script measures the internet download speed based on
# the download speed mean of wget while downloading a big file from a
# server.
# The file the script is going to try to download can be changed by the
# user in the “link” variable.
