Subject: [ANN] interface 0.1.0

Hi all,

It is with some trepidation that I announce the first release of the
interface module.

What is it?
===========
Java style interfaces for Ruby.  For example:

require "interface"

MyInterface = interface{
   required_methods :foo, :bar
}

# raises an Interface::MethodMissing error
class A
   include MyInterface
end

# Also raises an error
class B; end
b = B.new
b.extend(MyInterface)

# No error raised
class C
   def foo; end
   def bar; end
   include MyInterface
end

See the docs for more details, including a way to implement a partial
interface.

Where is it?
============
You can find it on the RAA or the project home page at
http://ruby-miscutils.sf.net.

Why did I do it?
================
Mainly to silence the Java weenies and to show that it was possible. 
See the README for the long version.  I, personally, do not find
interfaces to be especially useful, but here you go.

Enjoy! (or not)

Dan
