It's as easy as:

   perl -MCPAN -e'install Jifty'

   jifty app --name MyJiftyApp
   cd MyJiftyApp
   jifty model --name User


       column name =>
           type is 'text',
           is mandatory;
       column email =>
           type is 'text';

And then run this command to set up your database

   jifty schema --setup

When you're ready to use your (somewhat simplistic) new user database, start the standalone jifty server for your application:

   jifty server
