Auto User Creating Linux Script

Hi Experts,
I want Linux Script with following specifications.
*Create Linux users.
      usernames, passwords, home directories are in a seperate CSV (comma seperated file)configuration file. When I run the script, automatically users should created acording to the configuration file.

 Configuration file will looks as follows:
------------------------------------------------
   user1, password1, homedir1
   user2, password2, homedir2
   user3, password3, homedir3
-------------------------------------------------
(And if possible when I enter only the user name, password should automatically sets to the reverse word of the username , eg: 1resu)

And if users are already exist, then no need to create it again and after the script is over output(mentioning whether users have created or not) errors/details should write to a log file.

I would greatly appreciate your help.
