Constructors

Extends "Constructors" in User::Identity::Item.

$class->new( [$name], %options )
Create a new system. You can specify a name as first argument, or in the OPTION list. Without a specific name, the organization is used as name. 

 -Option     --Defined in          --Default
  description  User::Identity::Item  undef
  hostname                           'localhost'
  location                           undef

  os                                 undef
  parent       User::Identity::Item  undef
  password                           undef
  username                           undef
The $name of the described system. It is preferred to use full system names, not abbreviations. For instance, you can better use "www.tux.aq" than "www" to avoid confusion.
The $nick of a location which is defined for the same user. You can also specify a User::Identity::Location OBJECT.
The name of the operating system which is run on the server. It is advised to use the names as used by Perl's $^O variable. See the perlvar man-page for this variable, and perlport for the possible values.
The password to be used to login. This password must be un-encoded: directly usable. Be warned that storing un-encoded passwords is a high security list.
