+## Mass Useradd For Linux
+## This script that extracts new user data from a delimited text file,
+## and automatically generates new user accounts. It generates a random
+## password for each login, and exports the new logins and passwords to
+## a text file.  Passwords automatically expire at first login.  The
+## input file format is "username: full name" (no quotes) for each
+## line.
+##
+## Mass Useradd creates a "User Personal Group."
+## The UID and the GID are the same. User's home directories
+## are created with restrictive permissions, chmod 700.
+## Mass Useradd uses standard Shadow Suite utilities.
+## Values and behaviors are easily modifiable, according
+## to the individual utility being called.  It calls a companion
+## script, mass_passwd, to set each user password.  You should
+## have received mass_passwd from the same source as mass_useradd.
+##
+## This script was created by Aaron Malone, and modified by
+## Meredydd Luff, Peter Samuelson, and Kathryn Hogg.
+## Many thanks!
+## Carla Schroder wrote the documentation and pestered
+## the aforementioned persons to modify the original script.
