+# Program: /usr/sbin/adduser
+# Purpose: Interactive front end to /usr/sbin/useradd for Slackware Linux
+# Author : Stuart Winter <stuart@polplex.co.uk>
+#          Based on the original Slackware adduser by Hrvoje Dogan
+#          with modifications by Patrick Volkerding
+# Version: 1.09
+##########################################################################
+# Usage..: adduser [<new_user_name>]
+##########################################################################
+# History #
+###########
+# v1.09 - 07/06/04 
+#       * Added standard Slackware script licence to the head of this file.
+# v1.08 - 25/04/04
+#       * Disallow user names that begin with a numeric because useradd 
+#         (from shadow v4.03) does not allow them. <sw>
+# v1.07 - 07/03/03
+#       * When supplying a null string for the uid (meaning 'Choose next available'), 
+#         if there were file names in the range 'a-z' in the pwd then the 
+#         egrep command considered these files rather than the null string. 
+#         The egrep expression is now in quotes.  
+#         Reported & fixed by Vadim O. Ustiansky <sw>
+# v1.06 - 31/03/03
+#       * Ask to chown user.group the home directory if it already exists.
+#         This helps reduce later confusion when adding users whose home dir
+#         already exists (mounted partition for example) and is owned
+#         by a user other than the user to which the directory is being
+#         assigned as home.  Default is not to chown.
+#         Brought to my attention by mRgOBLIN. <sw>
+# v1.05 - 04/01/03
+#       * Advise & prevent users from creating logins with '.' characters
+#         in the user name. <sw>
+#       * Made pending account creation info look neater <sw>
+# v1.04 - 09/06/02
+#       * Catered for shadow-4.0.3's 'useradd' binary that no longer
+#         will let you create a user that has any uppercase chars in it
+#         This was reported on the userlocal.org forums
+#         by 'xcp' - thanks. <sw,pjv>
+# v1.03 - 20/05/02
+#       * Support 'broken' (null lines in) /etc/passwd and 
+#         /etc/group files <sw>       
+#       * For recycling UIDs (default still 'off'), we now look in 
+#         /etc/login.defs for the UID_MIN value and use it
+#         If not found then default to 1000 <sw>
+# v1.02 - 10/04/02
+#       * Fix user-specified UID bug. <pjv>
+# v1.01 - 23/03/02
+#       * Match Slackware indenting style, simplify. <pjv>
+# v1.00 - 22/03/02
+#       * Created
