mycompany.css

/* /web_mycompany/static/src/css/mycompany.css */

/* Header */
.openerp.production .company_logo {
    background: url('/web_mycompany/static/src/img/logo.png');
    /* width:180px; */
    /* height:46px; */
}

/* ... and similar CSS hacks ... */

mycompany.js

/* /web_mycompany/static/src/js/mycompany.js */

openerp.web_mycompany = function(openerp) {

var hostname = window.location.hostname,
    params = jQuery.param != undefined && jQuery.deparam(jQuery.param.querystring()),
    production = hostname == 'my.hostname.com' || hostname == 'alt.hostname.com' || params.production != undefined;
