-== 0.12, released 2010-01-02
-
-* Removed rr in favor to rspec mock framework
-* Improved output for thor -T
-* [#7] Do not force white color on status
-* [#8] Yield a block with the filename on directory
-
-== 0.11, released 2009-07-01
-
-* Added a rake compatibility layer. It allows you to use spec and rdoc tasks on
-  Thor classes.
-
-* BACKWARDS INCOMPATIBLE: aliases are not generated automatically anymore
-  since it wrong behavior to the invocation system.
-
-* thor help now show information about any class/task. All those calls are
-  possible:
-  
-    thor help describe
-    thor help describe:amazing
-
-  Or even with default namespaces:
-
-    thor help :spec
-
-* Thor::Runner now invokes the default task if none is supplied:
-
-    thor describe # invokes the default task, usually help
-
-* Thor::Runner now works with mappings:
-
-    thor describe -h
-
-* Added some documentation and code refactoring.
-
-== 0.9.8, released 2008-10-20
-
-* Fixed some tiny issues that were introduced lately.
-
-== 0.9.7, released 2008-10-13
-
-* Setting global method options on the initialize method works as expected:
-  All other tasks will accept these global options in addition to their own.
-* Added 'group' notion to Thor task sets (class Thor); by default all tasks
-  are in the 'standard' group. Running 'thor -T' will only show the standard
-  tasks - adding --all will show all tasks. You can also filter on a specific
-  group using the --group option: thor -T --group advanced
-  
-== 0.9.6, released 2008-09-13
-
-* Generic improvements
-
-== 0.9.5, released 2008-08-27
-
-* Improve Windows compatibility
-* Update (incorrect) README and task.thor sample file
-* Options hash is now frozen (once returned)
-* Allow magic predicates on options object. For instance: `options.force?`
-* Add support for :numeric type
-* BACKWARDS INCOMPATIBLE: Refactor Thor::Options. You cannot access shorthand forms in options hash anymore (for instance, options[:f])
-* Allow specifying optional args with default values: method_options(:user => "mislav")
-* Don't write options for nil or false values. This allows, for example, turning color off when running specs.
-* Exit with the status of the spec command to help CI stuff out some.
-
-== 0.9.4, released 2008-08-13
-
-* Try to add Windows compatibility.
-* BACKWARDS INCOMPATIBLE: options hash is now accessed as a property in your class and is not passed as last argument anymore
-* Allow options at the beginning of the argument list as well as the end.
-* Make options available with symbol keys in addition to string keys.
-* Allow true to be passed to Thor#method_options to denote a boolean option.
-* If loading a thor file fails, don't give up, just print a warning and keep going.
-* Make sure that we re-raise errors if they happened further down the pipe than we care about.
-* Only delete the old file on updating when the installation of the new one is a success
-* Make it Ruby 1.8.5 compatible.
-* Don't raise an error if a boolean switch is defined multiple times.
-* Thor::Options now doesn't parse through things that look like options but aren't.
-* Add URI detection to install task, and make sure we don't append ".thor" to URIs
-* Add rake2thor to the gem binfiles.
-* Make sure local Thorfiles override system-wide ones.

-= thor
-
-Map options to a class. Simply create a class with the appropriate annotations
-and have options automatically map to functions and parameters.
-
-Example:
-
-    class App < Thor                                                 # [1]
-      map "-L" => :list                                              # [2]
-
-      desc "install APP_NAME", "install one of the available apps"   # [3]
-      method_options :force => :boolean, :alias => :string           # [4]
-      def install(name)
-        user_alias = options[:alias]
-        if options.force?
-          # do something
-        end
-        # other code
-      end
-
-      desc "list [SEARCH]", "list all of the available apps, limited by SEARCH"
-      def list(search="")
-        # list everything
-      end
-    end
-
-Thor automatically maps commands as such:
-
-    thor app:install myname --force
-
-That gets converted to:
-
-    App.new.install("myname")
-    # with {'force' => true} as options hash
-
-1. Inherit from Thor to turn a class into an option mapper
-2. Map additional non-valid identifiers to specific methods. In this case, convert -L to :list
-3. Describe the method immediately below. The first parameter is the usage information, and the second parameter is the description
-4. Provide any additional options that will be available the instance method options.
-
-== Types for <tt>method_options</tt>
-
-* :boolean - is parsed as <tt>--option</tt> or <tt>--option=true</tt>
-* :string  - is parsed as <tt>--option=VALUE</tt>
-* :numeric - is parsed as <tt>--option=N</tt>
-* :array   - is parsed as <tt>--option=one two three</tt>
-* :hash    - is parsed as <tt>--option=name:string age:integer</tt>
-
-Besides, method_option allows a default value to be given, examples:
-
-    method_options :force => false
-    #=> Creates a boolean option with default value false
-
-    method_options :alias => "bar"
-    #=> Creates a string option with default value "bar"
-
-    method_options :threshold => 3.0
-    #=> Creates a numeric option with default value 3.0
-
-You can also supply <tt>:option => :required</tt> to mark an option as required. The
-type is assumed to be string. If you want a required hash with default values
-as option, you can use <tt>method_option</tt> which uses a more declarative style:
-
-    method_option :attributes, :type => :hash, :default => {}, :required => true
-
-All arguments can be set to nil (except required arguments), by suppling a no or
-skip variant. For example:
-
-    thor app name --no-attributes
-
-In previous versions, aliases for options were created automatically, but now
-they should be explicit. You can supply aliases in both short and declarative
-styles:
-
-    method_options %w( force -f ) => :boolean
-
-Or:
-
-    method_option :force, :type => :boolean, :aliases => "-f"
-
-You can supply as many aliases as you want.
-
-NOTE: Type :optional available in Thor 0.9.0 was deprecated. Use :string or :boolean instead.
-
-== Namespaces
-
-By default, your Thor tasks are invoked using Ruby namespace. In the example
-above, tasks are invoked as:
-
-    thor app:install name --force
-
-However, you could namespace your class as:
-
-    module Sinatra
-      class App < Thor
-        # tasks
-      end
-    end
-
-And then you should invoke your tasks as:
-
-    thor sinatra:app:install name --force
-
-If desired, you can change the namespace:
-
-    module Sinatra
-      class App < Thor
-        namespace :myapp
-        # tasks
-      end
-    end
-
-And then your tasks hould be invoked as:
-
-    thor myapp:install name --force
-
-== Invocations
-
-Thor comes with a invocation-dependency system as well which allows a task to be
-invoked only once. For example:
-
-    class Counter < Thor
-      desc "one", "Prints 1, 2, 3"
-      def one
-        puts 1
-        invoke :two
-        invoke :three
-      end
-
-      desc "two", "Prints 2, 3"
-      def two
-        puts 2
-        invoke :three
-      end
-
-      desc "three", "Prints 3"
-      def three
-        puts 3
-      end
-    end
-
-When invoking the task one:
-
-    thor counter:one
-
-The output is "1 2 3", which means that the three task was invoked only once.
-You can even invoke tasks from another class, so be sure to check the
-documentation.
-
-== Thor::Group
-
-Thor has a special class called Thor::Group. The main difference to Thor class
-is that it invokes all tasks at once. The example above could be rewritten in
-Thor::Group as this:
-
-    class Counter < Thor::Group
-      desc "Prints 1, 2, 3"
-
-      def one
-        puts 1
-      end
-
-      def two
-        puts 2
-      end
-
-      def three
-        puts 3
-      end
-    end
-
-When invoked:
-
-    thor counter
-
-It prints "1 2 3" as well. Notice you should describe (using the method <tt>desc</tt>)
-only the class and not each task anymore. Thor::Group is a great tool to create
-generators, since you can define several steps which are invoked in the order they
-are defined (Thor::Group is the tool use in generators in Rails 3.0).
-
-Besides, Thor::Group can parse arguments and options as Thor tasks:
-
-    class Counter < Thor::Group
-      # number will be available as attr_accessor
-      argument :number, :type => :numeric, :desc => "The number to start counting"
-      desc "Prints the 'number' given upto 'number+2'"
-
-      def one
-        puts number + 0
-      end
-
-      def two
-        puts number + 1
-      end
-
-      def three
-        puts number + 2
-      end
-    end
-
-The counter above expects one parameter and has the folling outputs:
-
-    thor counter 5
-    # Prints "5 6 7"
-
-    thor counter 11
-    # Prints "11 12 13"
-
-You can also give options to Thor::Group, but instead of using <tt>method_option</tt>
-and <tt>method_options</tt>, you should use <tt>class_option</tt> and <tt>class_options</tt>.
-Both argument and class_options methods are available to Thor class as well.
-
-== Actions
-
-Thor comes with several actions which helps with script and generator tasks. You
-might be familiar with them since some came from Rails Templates. They are:
-<tt>say</tt>, <tt>ask</tt>, <tt>yes?</tt>, <tt>no?</tt>, <tt>add_file</tt>,
-<tt>remove_file</tt>, <tt>copy_file</tt>, <tt>template</tt>, <tt>directory</tt>,
-<tt>inside</tt>, <tt>run</tt>, <tt>inject_into_file</tt> and a couple more.
-
-To use them, you just need to include Thor::Actions in your Thor classes:
-
-    class App < Thor
-      include Thor::Actions
-      # tasks
-    end
-
-Some actions like copy file requires that a class method called source_root is
-defined in your class. This is the directory where your templates should be
-placed. Be sure to check the documentation.
