Overview

Jabbot configuration. Use either Jabbot::CliConfig.new or JabbotFileConfig.new setup a new bot from either command line or file (respectively). Configurations can be chained so they override each other:

config = Jabbot::FileConfig.new
config << Jabbot::CliConfig.new
config.to_hash

The preceding example will create a configuration which is based on a configuration file but have certain values overridden from the command line. This can be used for instance to store everything but the Twitter account password in your configuration file. Then you can just provide the password when running the bot.
