HOMEWORK3.txt

Commit homework #2 to a 'homework' repo on github.com. Something like:
git://github.com/cbnoonan/homework.git/2/cogserver.py.

Given homework #2, copy it to a different location in the repo (like
3/cogserver2.py) and add the following features to it, via the
optparse module.

o Accept an optional host and port arguments. -o HOST (or --host=HOST)
and -p PORT (or --port=PORT). These default to Homework #2's values if
not defined.

o Accept an optional command line argument -e ENCODING (or
--encoding=ENCODING). When defined, makes the server encode the
accepted data from the client (the data printed to stdout) with that
encoder.

Output should be as follows:

$ python cogserver2.py --help
usage: cogserver2.py [options]

options:
  -h, --help            show this help message and exit
  -o HOST, --host=HOST  the host to bind/connect to
  -p PORT, --port=PORT  the port to bind/connect to
  -e ENCODING, --encoding=ENCODING
                        server's output encoding
