You need to use a combination of a few Cobalt functions. The easiest thing
is to use Perl, and use code like this (just an example -- the code has not
been tested):

use Cobalt::User;
use Cobalt::List;

sub userAlive
{
  $username = shift;
  return "User already exists in passwd file" if(
Cobalt::User::user_exist( $username ) );
  return "Alias already exist with that name" if(
Cobalt::List::alias_exist( $username ) );
  return "List already exist with that name" if( Cobalt::List::list_exist(
$username ) );
  return "All clear";
}

Remember to check for things like people wanting to add users named "admin",
"wheel" and similar fun stuff.
