"""webClient for  Python

author: michael branton

usage: webClient.py wireTAPhost port wireTAPchannel url  wraplength sleeptime {debug}

this connects you to / website specified by a url, from
which data may be downloaded. specifying any value at all 
for the debug parameter causes the data to also be dumped 
to the screen. wraplength will wrap the text to that length
