User Manager and useradd

[Tim Alberts]

I am working on scripts to manage user accounts a little easier.  In the
User Manager GUI app there is a field 'Full Name'.  However, the CLI
command 'useradd' does not have a field for 'Full Name'.  It does have a
'comment' field (The new user's password file comment field) as shown in
'man useradd'.  Question, are these two the same field and if not, where
is the 'Full Name' data stored by User Manager and what exactly is the
comment field of the 'useradd' command?
