Get from
./configure --prefix=/usr/local --enable-gui=no
sudo make install

class DBUtil < ActiveRecord::Migration
def self.create_history(table, history_table, columns, to_use)

class CreateUsers < ActiveRecord::Migration
require File.expand_path('db/dbutil.rb')
def self.up
create_table :users do |t|
