#     setup-local-client.sh  - setup root credentials
#     setup-local-client.sh user1  - set up user1 credentials and store in 
#                      $HOME/.xcat
#     setup-local-client.sh user2  /tmp/user2  - setup user2 credentials and
#                      store in /tmp/user2/.xcat.  Must later be copied to 
#                      $HOME/xcat for user2.  Used when root cannot write to
#                      the home directory of user2 (e.g when mounted).
