#   * add option to read list of URLs from file
#   * support HTTP Basic Authentication somehow.  Note that currently, this
#       reads local files even when they should be protected by .htaccess
#       (unless using -h option).
#   * Read list of local host names from gethostbyname() ?
#   * check read permissions on files?
#   * In the event multiple URLs redirect to the same URL, this could be a
#       little more efficient if it saved the redirected loads/downloads.
