=head1 NAME

Class::PublicPrivate - Class with public keys with any name and a separate set
of private keys

=head1 SYNOPSIS

PublicPrivate is intended for use as a base class for other classes.  Users of
class based on PublicPrivate can assign any keys to the object hash without
interfering with keys used internally.  The private data can be accessed by
retrieving the private hash with the C<private> method.  For example, the
following code outputs two different values, one for the public value of
C<start> and another for the private value of C<start>.

 package ExtendedClass;
 use base 'Class::PublicPrivate';

 sub new{
    my $class = shift;
    my $self = $class->SUPER::new();
    my $private = $self->private;

    # initialize one of the private properties
    $private->{'start'}=time();

    return $self;
 }

 package main;
 my ($var);
 $var = ExtendedClass->new();
 $var->{'start'} = 1;

 print $var->{'start'}, "\n";
 print $var->private()->{'start'}, "\n";

=head1 INSTALLATION

Class::PublicPrivate can be installed with the usual routine:

	perl Makefile.PL
	make
	make test
	make install

You can also just copy PublicPrivate.pm into the Class/ directory of one of
your library trees.

=head1 METHODS

=head2 YourClass->new(classname ,[initikey1=>initvalue [, ...]])

Returns an instantiation of YourClass, where YourClass is a class that extends
Class::PublicPrivate.  Additional key=>value pairs are stored in the private
hash.  Programs that use your class can store any date directly in it w/o
affecting the object's private data.

=head2 $ob->private()

Returns a reference to the hash of private data.
