Very good suggestion @Ray:

@Fabian you can do it following way:

In the __openerp__.py file, need to add 'auto_install': True as shown in the below example(it is from web_calendar module).

{
    'name': 'Web Calendar',
    'category': 'Hidden',
    'description':"""
OpenERP Web Calendar view.
==========================
""",
    'author': 'OpenERP SA, Valentino Lab (Kalysto)',
    'version': '2.0',
    'depends': ['web'],
    'data' : [
        'views/web_calendar.xml',
    ],
    'qweb': [
        'static/src/xml/*.xml',
    ],
    'auto_install': True
}
