ORBit is a high-performance CORBA (Common Object Request Broker
Architecture) ORB (object request broker). It allows programs to
send requests and receive replies from other programs, regardless
of the locations of the two programs. CORBA is an architecture that
enables communication between program objects, regardless of the
programming language they're written in or the operating system they
run on.

You will need to install this package if you want to run programs that use
the ORBit implementation of CORBA technology.
