Here is how this script works:

◆ It first gets a list of users by calling the getUsers()function This func-tion is given the PASSWD_FILE file name, which is configured in reminder.conf The user list is returned into $userList.

◆ For each user in $userList, the script calls the doRemind()function, which processes the reminders for the user.
