discuss: License approval for TAO and ACE

[Malcolm Spence]

[ please discuss this license.  -russ ]

Dear sir, we distribute a commercial product set to support ACE and TAO. ACE
is a C++ patterns software for porting across platforms. TAO is a CORBA 2.6
implementation built on ACE.

We make a nominal charge for CDs ($50 on windows, $75 for multiple Unix
platforms). All Cds can be copied anywhere and are builds for various
compilers, with automated install programs. We include all the source, test
programs, benchmarking software etc. We also have the source and all patches
for free download off our web site. Our version is derived from the
Washington University of St Louis beta code. All changes get rolled back
into the beta code as well as patched into our stable version. We issue new
versions about once a year.

Below is our license which includes the original Wash U license and some Sun
licenses to do with CORBA elements that Sun developed and a license for
GPERF which is sometimes used as part of TAO development cycle.

The licensing is intended to be generous to enable companies to use open
source CORBA in their infrastructure with no concerns, and to encourage its
use in commercial products. Our goal is to ensure open source, standards
based, infrastructure as a way to ensure open systems development and the
promotion of choice.

Licensing Terms:
Introduction
TAO is made available under the "open source software" model. The source is
freely downloadable, open for inspection, review and comment. Copies may be
freely installed across all your systems and those of your customers. The
source code is designed to be compiled and used across a wide variety of
hardware and operating systems architectures. Target systems include UNIX
systems, including Linux; MS Windows platforms, and real time platforms such
as VxWorks, Lynx and pSOS.

The ACE ORB source code is copyrighted by Dr. Douglas C Schmidt and the
Distributed Object (DOC) research group at Washington University in St.
Louis. The actual terms are given below, are also included in TAO
documentation from OCI and the OCI distributions of TAO on CDs. TAO is made
available by means of an open source model. TAO may be used without the
payment of development license or run time fees. It also means that the TAO
source may be made available along, with any added value products, which
utilize TAO. The distributions on CD contain the source code for ACE and
TAO, in accordance with those requirements.

TAO also includes software from Sun Microsystems. This software is related
to the IDL compiler and IIOP. This software also may be freely distributed
without fees. The licensing details are included below.

TAO under certain circumstances also uses a software program called GPERF.
This software was also written by Dr. Schmidt and is licensed under the
terms of the Free Software Foundation's GNU Public License (GPL). Details on
this licensing may also be found below.

Please read the licensing information prior to purchase if you have any

Copyright and Licensing Information for GPERF
GPERF is a standalone software program. GPERF generates perfect hash
functions for lookups based on a set of key words when the key words are
known in advance. They are called perfect hash functions because only a
single access into the data structure is needed in order to perform a
lookup. When the set of IDL operations is known in advanced TAO uses the
perfect hash functions generated by GPERF in order to perform the operation
lookup in constant time. Similarly servant lookups can be done, if the set
of servants is known in advanced.

GPERF was originally developed by Professor Douglas Schmidt. Professor
Schmidt subsequently signed the copyright over to the Free Software
Foundation, causing gperf to be licensed under the GPL (GNU General Public
License).  The FSF still maintains that version of gperf.  When perfect
hashing was added as an option to TAO, gperf was selected to provide that
function. It was extended and enhanced to meet the more demanding needs of
TAO and a derived version was placed in the ACE application libraries.  When
using TAO under certain circumstances you may elect to use that version of
gperf, which is part of the ACE distribution of examples and optional
programs.  Both the current FSF gperf and the ACE gperf are based on the
original implementation.  Since the ACE gperf is derived from the original
GPL'ed version, it too is licensed under the GPL.

The following terms are found in the source files for gperf:
