    this class resulted from extracting WIN32 specifics of the old

    OperatingSystemClass into this sub-class.

    You may find some leftover unix stuff, which will go away sooner

    or later.

    this class realizes access to most (all ?) required operating system services;

    some of it is very specific for unix, so do not depend on

    things available here in your applications

    - some may not be found in other OS's or be slightly different ...

    (On the other hand: I do not want to hide all features

     from you - in some situations it MAY be interesting to be

     able to get down to a select or fork system call easily (at least on Unix systems).

     You decide - portability vs. functionality)

    [Class variables:]

	HostName        <String>        remembered hostname

	DomainName      <String>        remembered domainname

	CurrentDirectory <String>       remembered currentDirectories path
