NAME
       User::Identity::System - physical system of a person

INHERITANCE
        User::Identity::System
          is a User::Identity::Item

SYNOPSIS
        use User::Identity;
        use User::Identity::System;
        my $me   = User::Identity->new(...);
        my $server = User::Identity::System->new(...);
        $me->add(system => $server);

        # Simpler

        use User::Identity;
        my $me   = User::Identity->new(...);
        my $addr = $me->add(system => ...);

DESCRIPTION
       The "User::Identity::System" object contains the description of the user's presence on a
       system.  The systems are collected by an User::Identity::Collection::Systems object.

       Nearly all methods can return undef.

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

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

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

       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.

            -Option     --Defined in          --Default
             description  User::Identity::Item  undef
             hostname                           'localhost'
             location                           undef
             name         User::Identity::Item  <required>
             os                                 undef
             parent       User::Identity::Item  undef
             password                           undef
             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.

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

       $obj->description()
           Inherited, see "Attributes" in User::Identity::Item

       $obj->hostname()
       $obj->location()
           Returns the object which describes to which location this system relates.  The
           location may be used to find the name of the organization involved, or to create a
           signature.  If no location is specified, undef is returned.

       $obj->name( [NEWNAME] )
           Inherited, see "Attributes" in User::Identity::Item

       $obj->os()
       $obj->password()
       $obj->username()

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

       $obj->add(COLLECTION, ROLE)
           Inherited, see "Collections" in User::Identity::Item

       $obj->addCollection(OBJECT | ([TYPE], OPTIONS))
           Inherited, see "Collections" in User::Identity::Item

       $obj->collection(NAME)
           Inherited, see "Collections" in User::Identity::Item

       $obj->find(COLLECTION, ROLE)
           Inherited, see "Collections" in User::Identity::Item

       $obj->parent( [PARENT] )
           Inherited, see "Collections" in User::Identity::Item

       $obj->removeCollection(OBJECT|NAME)
           Inherited, see "Collections" in User::Identity::Item

       $obj->type()
       User::Identity::System->type()
           Inherited, see "Collections" in User::Identity::Item

       $obj->user()
           Inherited, see "Collections" in User::Identity::Item

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.
