=== Program Name and valid command line arguments ===
Name your Python3 script as <code>ur_[student_id].py</code>. Create a symbolic link to your script as ur.py (e.g. use the command ln -s ur_rchan.py ur.py to create the line) so that you can refer to your script as ur.py. Your script must accept one or more "file name" as its command line parameters and other optional parameters as shown below. Your python script should produce the following usage text when run with the --help option:
<pre>
[rchan@centos7 a1]$ python3 ./ur.py -h
