This is a very simple (almost tutorial) application in Merb framework taken from this SLAPP tutorial .

A little bit of additional AJAX & theming was added. All credit goes to the original author.

Some shortcuts:

• rake db:migrate to generate database (sqlite3 config by default)
• rake spec to run the tests
• merb -t interactive merb console
• rake db:create:all create databases for all configurations
• rake db:test:clone recreate the test database from the current database
