Setup Scripts

[Alan McDonald]

Can someone tell me where to find setup scripts for the following:
I need to setup a mini WebHosting environment.
I want a script to add a user/password, create a home dir, create a symlink
for it from home/usr to var/www/html, to create domain host header, to add
postfix user account so this user can manage their own email for the domain,
etc and maybe other things to fit in with this need.
thanks
Alan
