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. 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. 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. 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.

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:

This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
