python /usr/local/lib/python/urllib.py  [ and one or more url's ] 
will write the sources to stdout.
Or use the functions in urllib to fetch them and do something 
else with them, like parse and fetch other referenced url's ( and
keep the ones already fetched in a dictionary, so you can check if
you've already retrieved it. )
