The User Profile Class

The User profile class manages what we know about a user on this host. This can for example be the FQDN of the host, the user's email address, the time zone, the news server etc. Note that this information does not correspond to the actual information for the host but instead represents "the information that the user wants to show the world". The user may use an arbitrary email address to be used in a HTTP request, for example. The application may assign a context to each use which gives the application to extend the use of this class.
