Liars is a tiny MVC web framework.
==================================

"liars" = "#{'rail'.reverse}s".
It's a very quick and dirty hack, just demonstrating some concepts. As its name said, Don't trust it. :-)

Install
=======

    gem install liars.


Usage
=====

1. Create a new scaffold file. The command below generates a scaffold ruby file named test.rb.
    liars -s test
2. Run it. The command below also generates a database file named db.yaml.
    liars test.rb
3. Now lauch your browser to <http://localhost:2008>

Help
====

    liars --help

An extra blog example:
======================

Copy code below blog.rb to a new ruby file such as blog.rb, then run:

    liars blog.rb -d blog.yaml

blog.rb:

    module Liars
      # Model ======================================================================
      class Article < M
        has_field :title
        has_field :content
        has_many :comments
      end

      class Comment < M
        has_field :title
        has_field :content
        belongs_to :article
      end

      class ArticleC < C
