From the developer:
Web hosting control panel software for Mac OS X (desktop and server) .iTools is a web site management system for both small to medium-sized web hosting providers that own or rent dedicated servers, and for large service providers who may wish to bundle iTools into their offerings. iTools is ideal for the professional hosting of multiple companies on a single server; it shortens the time and lessens the expertise needed to deploy new sites.
