    Games::Lacuna::Client - An RPC client for the Lacuna Expanse

      use Games::Lacuna::Client;
      my $client = Games::Lacuna::Client->new(cfg_file => 'path/to/myempire.yml');

      # or manually:
      my $client = Games::Lacuna::Client->new(
        uri      => 'https://path/to/server',
        api_key  => 'your api key here',
        name     => 'empire name',
        password => 'sekrit',
        #session_peristent => 1, # only makes sense with cfg_file set!
        #debug    => 1,

      my $res = $client->alliance->find("The Understanding");
      my $id = $res->{alliances}->[0]->{id};

      use Data::Dumper;
      print Dumper $client->alliance->view_profile( $res->{alliances}->[0]->{id} );

    This module implements the Lacuna Expanse API as of 10.10.2010.

    You will need to have a basic familiarity with the Lacuna RPC API
    itself, so check out <http://gameserver.lacunaexpanse.com/api/> where
    "gameserver" is the server you intend to use it on. As of this writing,
    the only server is "us1".

    The different API *modules* are available by calling the respective
    module name as a method on the client object. The returned object then
    implements the various methods.

    The return values of the methods are (currently) just exactly "result"
    portion of the deflated JSON responses. This is subject to change!

    On failure, the methods "croak" with a simple to parse message. Example:

      RPC Error (1002): Empire does not exist. at ...

    The number is the error code number (see API docs). The text after the
    colon is the human-readable error message from the server.

    You do not need to login explicitly. The client will do this on demand.
    It will also handle session-timeouts and logging out for you. (Log out
    happens in the destructor.)

    All methods that take a session id as first argument in the JSON-RPC API
    DO NOT REQUIRE that you pass the session_id manually. This is handled
    internally and the client will automatically log in for you as

        name      => 'My empire',                # empire_name in config file
        password  => 'password of the empire',   # empire_password in config file
        uri       => 'https://us1.lacunaexpanse.com/',   # server_uri in config file
        api_key   => 'public api key',

    Some of the parameters of the constructor can also be supplied in a
    configuration file in YAML format. You can find a template in the
    examples subdirectory.

      empire_name: The name of my Empire
      empire_password: The password
      server_uri: https://us1.lacunaexpanse.com/

      uri:        will overwrite the server_uri key (might be a bug)

      open_captcha: 1   # Will attempt to open the captcha URL in a browser,
                        # and prompts for the answer. If the browser-open fails,
                        # falls back to prompt_captcha behaviour if that setting
                        # is also true
      prompt_captcha: 1 # Will print an image URL, and prompts for the answer

    A few ready-to-use tools of varying quality live in the examples
