'''
This script allows you to use bitvisitor.com without having to open it in a webbrowser. 
However, you will still have to wait the 5 minutes and enter the captchas manually. 
It is mainly a console application, but a small window will ask you for the captchas. 

This script was tested with Python 2.7 on Windows 7. Besides the standard stuff, 
it depends on BeautifulSoup (http://www.crummy.com/software/BeautifulSoup/) 
and PIL (http://www.pythonware.com/products/pil/). 

usage: pyvisitor.py [-h] [-u path] [-a address]        (all arguments are optional)

optional arguments:
  -h, --help                      Show this help message and exit.
  -u path, --user-agents path     A path to a file containing a user-agent on each line.
  -a address, --address address   Your bitcoin address. If omitted, you will be prompted.
