Using PolyORB as DSA PCS
========================

PolyORB provides an application personality that implements a Partition
Communication Subsystem for the Distributed Systems Annex of the Ada
language, in conjunction with the GNAT compiler. In order to use this
personality, you need to use matching releases of the compiler and
middleware.

The following combinations of releases are known to be compatible:

GNAT version  | PolyORB version
--------------+-----------------
GNAT Pro 6.0  | PolyORB 2.2
GNAT Pro 6.1  | PolyORB 2.3
GNAT GPL 2008 | PolyORB 2.4
GNAT Pro 6.2  | PolyORB 2.5
GNAT GPL 2009 | PoylORB GPL 2009
GNAT Pro 6.3  | PolyORB 2.6
GNAT GPL 2010 | PoylORB GPL 2010
GNAT Pro 6.4  | PolyORB 2.7
GNAT Pro 7.0  | PolyORB 2.8
GNAT GPL 2012 | PoylORB GPL 2012
GNAT Pro 7.1  | PolyORB 2.9
GNAT Pro 7.2  | PolyORB 2.10
GNAT Pro 7.3  | PolyORB 2.11
GNAT Pro 7.4  | PolyORB 2.12

Subsequent versions of GNAT Pro and PolyORB (starting with GNAT Pro 17
and PolyORB 17) follow consistent numbering schemes. Compatibility is
guaranteed for GNAT and PolyORB versions bearing the same major release
number.
