Creates and returns a class that includes the ExampleGroupMethods module. Which ExampleGroup type is created depends on the directory of the file calling this method. For example, Spec::Rails will use different classes for specs living in spec/models, spec/helpers, spec/views and spec/controllers.
It is also possible to override autodiscovery of the example group type with an options Hash as the last argument:
describe "name", :type => :something_special do ...
The reason for using different behaviour classes is to have different matcher methods available from within the describe block.
See Spec::Example::ExampleFactory#register for details about how to register special implementations.

23: raise ArgumentError if args.empty?
24: raise ArgumentError unless block
25: args << {} unless Hash === args.last
26: args.last[:spec_path] = caller(0)[1]

Creates a Shared Example Group and assigns it to a constant
share_as :AllEditions do
it "should do all editions stuff" ...
end
describe SmallEdition do
it_should_behave_like AllEditions
it "should do small edition stuff" do
...
end
end
And, for those of you who prefer to use something more like Ruby, you can just include the module directly
describe SmallEdition do
include AllEditions
it "should do small edition stuff" do
...
end
end

Creates an example group that can be shared by other example groups
share_examples_for "All Editions" do
it "all editions behaviour" ...
