README files
============

README.win32.txt - contains important information on building and
                   using omniORB on Windows NT and Windows 95.

README.unix -      contains important information on building and
                   using omniORB on Unix platforms.

Other readmes live the the readmes/ subdirectory. See if there is one
for your platform.



Technical Highlights
====================

omniORB is an Object Request Broker (ORB) which implements
specification 2.6 of the Common Object Request Broker Architecture
(CORBA).

- C++ language bindings are supported. The mapping conforms to the
  latest revision of the CORBA specification.

- support for the Portable Object Adapter (POA)

- support for the Interoperable Naming Service (INS)

- The Internet Inter-ORB Protocol (IIOP 1.2) is used as the native
  protocol.

- The omniORB runtime is fully multithreaded. It uses native platform
  thread support encapsulated with a small class library, omnithread,
  to abstract away from differences in native thread APIs.

- TypeCode and type Any are supported.

- DynAny is supported.

- The Dynamic Invocation and Dynamic Skeleton interfaces are supported.

- Valuetype and abstract interfaces are supported.

- A COS Naming Service, omniNames, is provided.

- Many platforms are supported, including most Unix platforms and
  Windows.

  It should be straightforward to port omniORB to any platform which
  supports POSIX style threads, BSD style sockets and has a decent C++
  compiler which supports thread-safe exceptions. See readmes/PORTING
  for more information.

- It has been successfully tested for interoperability via IIOP with
  other ORBs.


Work in progress
================

omniORB is not yet a complete implementation of the CORBA core. The
following features are not supported in the current release.

- Portable Interceptors.
- Asynchronous Message Interface.


Missing features
================

The following features are missing from omniORB. We are not currently
planning on adding support for these features.

- omniORB does not have its own Interface Repository. However, the
  omniifr project aims to create one. See

    http://sourceforge.net/projects/omniifr/


Installation	
============

Installation instructions are provided in the following files:

- README.unix      for all unix platforms

  provide specific information about the directories and files, tools
  and examples.  You may want to explore the tree to become familiar
