Tern - The SQL Fan's Migrator
===============================

Tern is designed to simplify migrating database schemas with views, 
functions,
triggers, constraints and other objects where altering one may require 
dropping
and recreating others. For example, if view A selects from view B which 
selects
from table C, then altering  C could require five steps: drop A, drop B, 
alter
C, recreate B, and recreate A. Tern can be told to alter C and it will
automatically perform the other four steps.

Installation
============

     gem install tern
