          HELP SECTION FOR ADDING USER SCRIPT
 ----------------------------------------------------------------------------
 This script is made to read details from a file regarding user
 accounts and to create those accounts as appropriate.
 ----------------------------------------------------------------------------
 Only the root/administrative user, or user with administrative
 rights may use this script.
 ----------------------------------------------------------------------------
 The file that it reads from, 'userlist.txt', should exist. If that file
 does not exist (in the same directory), or is empty, there is no
 purpose for this script and it will not proceed.
 ----------------------------------------------------------------------------
 The structure of userlist.txt should be as follows:
 username:password:groupname:fullname
 Please do not use any spaces. No fields may be left blank.
 Any users with blank/invalid data will be skipped.
 ----------------------------------------------------------------------------
 Logs are stored in a file in the same directory called 'report.log'.
 If this file does not exist, it will be created.
