I created a small module in Openerp 7.0. Tried to add it the way we do in 6.1, but cannot find my module. Am I missing something? Please help. __init__.py:

import demo

__openerp__.py

{
    'name' : 'Demo',
    'version' : '1.1',
    'author' : 'OpenERP SA',
    'category' : 'Tools',
    'description' : 'First module in 7.0',
    'website': 'http://www.evontech.com',
    'images' : [],
    'depends' : ['base_setup'],
    'data': ['demo_view.xml'],
    'installable': True,
    'auto_install': False,
}

demo.py

from openerp import netsvc

class demo(osv.osv):
    _name = 'demo'
    _columns = {
                    'name':fields.char('Name', size=50),
                }
demo()
