User::Identity::System->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.

      description  User::Identity::Item  undef
      hostname                           'localhost'

      username                           undef

    description => STRING
    hostname => DOMAIN
        The hostname 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.

    location => NICKNAME|OBJECT
        The NICKNAME of a location which is defined for the same user. You can also specify a User::Identity::Location OBJECT.

    name => STRING
    os => STRING
        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.

    parent => OBJECT
    password => STRING
        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.

    username => STRING
        The username to be used to login to this host.

$obj->hostname()
$obj->location()

DIAGNOSTICS

Error: $object is not a collection.
    The first argument is an object, but not of a class which extends User::Identity::Collection.

Error: Cannot load collection module for $type ($class).
    Either the specified $type does not exist, or that module named $class returns compilation errors. If the type as specified in the warning is not the name of a package, you specified a nickname which was not defined. Maybe you forgot the 'require' the package which defines the nickname.

Error: Creation of a collection via $class failed.
    The $class did compile, but it was not possible to create an object of that class using the options you specified.

Error: Don't know what type of collection you want to add.
    If you add a collection, it must either by a collection object or a list of options which can be used to create a collection object. In the latter case, the type of collection must be specified.

Warning: No collection $name
    The collection with $name does not exist and can not be created.
