Before electronically submitting you should have a compressed tar file, e.g., file.tar.gz sitting in your CS account. If you develop elsewhere, first sftp the tarball to your CS account:
  1. sftp the gzipped tar file to your CS account: 
    	[andrewd@rafiki] ~/ > sftp access.cs.clemson.edu
	andrewd@access.cs.clemson.edu's password: 
	sftp> put file.tar.gz
	file.tar.gz                 |       1273 kB | 1273.9 kB/s | TOC: 00:00:01 | 100%
	sftp> quit
  2. Now log in to your CS account: 
    	[andrewd@rafiki] ~/ > ssh access.cs.clemson.edu
	andrewd@access.cs.clemson.edu's password: 
	Authentication successful.
  3. Then submit your electronic gzipped tape archive file. Open up the web page at: https://handin.cs.clemson.edu
