// AddMessage.java: ITX directory application to add a message
// to the directory entry for the user who launched this program.
// The user must already be in the directory (see AddNewUser).

// Caution: very insecure.  Password is given either on the argument line
//          or typed into the keyboard.  Sorta matches directory, though.

// Usage:  java AddMessage [ userid | [ password ]]
