=head1 NAME

Net::ACL::Set - Abstract parent class of Set-classes

=head1 SYNOPSIS

    package Net::ACL::SetMyPackage;

    use Net::ACL::Set;
    @ISA     = qw( Net::ACL::Set );

    sub new { ... };
    sub set { ... };


    package main;

    # Construction
    my $set = new Net::ACL::SetMyPackage($args);

    # Accessor Methods
    @data = $set->set(@data);

=head1 DESCRIPTION

This is an abstract parent class for all Net::ACL::Set*
classes. It is used by the Net::ACL::Rule object.

It only has a constructor new() and a method set(). Both should be
replaced in any ancestor object.

=head1 CONSTRUCTOR

=over 4

=item 4 new() - Constructor of Net::ACL::Set* objects

    my $set = new Net::ACL::SetMyPackage($args);

This is the constructor for Net::ACL::Set::* objects.
It returns a reference to the newly created object.
It takes one argument, which should describe what to set.

=head1 ACCESSOR METHODS

=over 4

=item set()

This function should modify the data given as arguments (one or more) with
the data passed to the constructor and return the modified data.
