""" Automate the download of availlable manual.

    This script automates the download of manual for every languages availlable,
    from the specifyed server (see at the bottom of the script) as long as the
    server follows this tree:
        server_path/language/manual.zip

    To use it, you have to modify the server URL at the bottom of the script
    (variable "base_url"),
    and modify the last line of the script to tell which kind of manual it is
    ("installer" or "mcc")
