'''getPageFromURL.py

   Jeff Ondich, 16 Jan 2009

   This program gives a brief illustration of how to use
   the urllib2 module to retrieve files stored on the
   network.  The program accepts an URL as a command-line
   argument, retrieves the text of the file specified by
   that URL, and prints the text to standard output.
