=head1 NAME

Oyster::Provision - Provision an Oyster

=head1 SYNOPSIS

    my $server = Oyster::Provision->new(
        name => 'Ostrica',
        size => '256',
        image => 'Meerkat',
        pub_ssh => "$ENV{HOME}/.ssh/id_rsa.pub",
    );
    $server->create;

=head1 BACKENDS

By default, the L<Oyster::Provision::Rackspace> backend
will be used.

Each backend needs to accept at least the C<name>,
C<size>, C<image> and C<pub_ssh> parameters. The meaning
of these parameters may differ from one backend to another.

=head1 METHOS

Each backend usually implements the following C<required>
methods:

=over

=item create

Creates a new server by given name, if such server does
not exist.

Installs the required packages for the distribution

=item delete

Gets rid of the server instance

=item resize

Hopefully scales the server
