Grails stands for Groovy on Rails and aims to bring the "coding by convention" paradigm to Groovy.
Grails leverages industry proven Open Source technology such as Spring, Hibernate, SiteMesh and the Groovy language to provide a flexible framework for building web applications.

虽然还没有发布官方消息, 但cvs上已增加了ajax, blog两个sample, 官方站点已有详细Installation, Quick Start, User Guide, Tutorial, 看来发展良好.
grails实际是groovy on spring, 没有xml配置(最期待的).
