Lab 5 - Bittorrent
http://www.cs.swarthmore.edu/~aviv/classes/f12/cs43/labs/lab5/lab5.pdf

#################################
# OVERVIEW 
#################################

In this lab we implement a bittorrent client(/server) which
accepts a number of peers as command line arguments or as
incoming connections via the bittorrent handshake protocol.

This is N-Peers with Restarts

#################################
# IMPLEMENTATION NOTES 
#################################

We believe the functions are written as you expect that we
wrote them.  A few notes:

- We implemented symmetrically from the start - 
  We poll all file descripters (including the incoming fd) using
  fd sets.  This implementation is very closesly related to the
  one Beejus gave in his guide to network programming

- Logging is done via a log_record function which is a wrapper
  around vprintf and accepts formatted strings

- Supports starting with partial files

You can make the bt_client executable via the make command in the root directory

Running ./bt_client without aguments will show usage information
