Merb

At the time of writing, Merb 1.0.15 has been released.

Execute the following: jgem install merb-core merb-more

There're currently Active Record and Sequel ORMs working properly with Merb. Both will require additional jdbc drivers (jgem install postgres-pr for PostgreSQL driver). DataMapper support is in development.

You can also Debug Merb Application with Netbeans.
