Gaelyk is a lightweight Groovy toolkit for developing and deploying Groovy applications on Google App Engine.

Gaelyk is a thin layer on top of the Google App Engine SDK, that is aimed at simplifying the creation of applications written in the Groovy dynamic language to be deployed on GAE. Thanks to Groovlets (servlet scripts basically) and templates, and entities, you can follow an MVC paradigm for creating your applications. Several nice syntax shortcuts simplify the usage of the low-level SDK APIs, such as an email.send to: "" shorthand and more.

If you want to learn more about this little framework, please have a look at the extensive tutorial.

Gaelyk was also presented recently at the Devoxx conference in Belgium, along with Patrick Chanezon descripting the GAE platform.
