    root nil, :desc => "Adhearsion application root folder"

    lib "lib", :desc => <<-__
      Folder to include the own libraries to be used. Adhearsion loads any ruby file
      located into this folder during the bootstrap process. Set to nil if you do not
      want these files to be loaded. This folder is relative to the application root folder.
    __

    environment :development, :transform => Proc.new { |v| v.to_sym }, :desc => <<-__
      Active environment. Supported values: development, production, staging, test
    __

    process_name "ahn", :desc => <<-__
      Adhearsion process name, useful to make it easier to find in the process list
      Pro tip: set this to your application's name and you can do "killall myapp"
      Does not work under JRuby.
    __

    desc "Log configuration"
    logging {
      level :info, :transform => Proc.new { |v| v.to_sym }, :desc => <<-__
        Supported levels (in increasing severity) -- :trace < :debug < :info < :warn < :error < :fatal
      __
      outputters ["log/adhearsion.log"], :transform => Proc.new { |val| Array(val) }, :desc => <<-__
        An array of log outputters to use. The default is to log to stdout and log/adhearsion.log.
        Each item must be either a string to use as a filename, or a valid Logging appender (see http://github.com/TwP/logging)
      __
      formatter nil, :desc => <<-__
        A log formatter to apply to all active outputters. If nil, the Adhearsion default formatter will be used.
      __
    }

    after_hangup_lifetime 1, :transform => Proc.new { |v| v.to_i }, :desc => <<-__
      Lifetime of a call after it has hung up. Should be set to the minimum functional value for your application. Call actors (threads) living after hangup consume more system resources and reduce the concurrent call capacity of your application.

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *args, &block) ⇒ Object

Wrapper to access to a specific configuration object

Adhearsion.config.foo => returns the configuration object associated to the foo plugin

Handle the Adhearsion platform configuration
