[cs615asa] hw3 invocations

Sorry for the inconvenience,

The start instance command is invoked by "sh ec2-start-instance.sh -a" 
for the default AMI and "sh ec2-start-instance -a [ami]" for a specific 
ami. I re-read the man page and now I see the -a option was supposed to 
be optional. Running start instance as "sh ec2-start-instance.sh" will 
print a usage statement (as well as specifying a -h).

ec2-backup is run by invoking "python ec2-backup.py -d [dir]" or "python 
ec2-backup.py -t backup -m rsync -d /"

 From what you describe you want the commands to run without using the 
keywords python and sh. Without a compiled binary, how can someone do this?

Also, I realize I sent you a pdf file with my comments on the project. 
Would you prefer a plain text file?

Sorry again,
-Vincent
