*
* The Harvest software was developed by the Internet Research Task
* Force Research Group on Resource Discovery (IRTF-RD):
*
* Mic Bowman of Transarc Corporation.
* Peter Danzig of the University of Southern California.
* Darren R. Hardy of the University of Colorado at Boulder.

* This copyright notice applies to software in the Harvest

* Harvest source code distribution.
*
* TERMS OF USE
*
* The Harvest software may be used and re-distributed without
* charge, provided that the software origin and research team are
* cited in any use of the system. Most commonly this is
* accomplished by including a link to the Harvest Home Page
* (http://harvest.cs.colorado.edu/) from the query page of any
* Broker you deploy, as well as in the query result pages. These
* links are generated automatically by the standard Broker
* software distribution.

* consequential damages. Proper use of the Harvest software is
* entirely the responsibility of the user.
*
* DERIVATIVE WORKS
*
* Users may make derivative works from the Harvest software, subject
* to the following constraints:
*
* - You must include the above copyright notice and these
* accompanying paragraphs in all forms of derivative works,
* and any documentation and other materials related to such
* distribution and use acknowledge that the software was
* developed at the above institutions.
*
* - You must notify IRTF-RD regarding your distribution of
* the derivative work.
*
* - You must clearly notify users that your are distributing
* a modified version and not the original Harvest software.
*
* - Any derivative product is also subject to these copyright
* and use restrictions.
*
* Note that the Harvest software is NOT in the public domain. We
* retain copyright, as specified above.
*
* HISTORY OF FREE SOFTWARE STATUS
*
* Originally we required sites to license the software in cases
* where they were going to build commercial products/services
* around Harvest. In June 1995 we changed this policy. We now
* allow people to use the core Harvest software (the code found in
* the Harvest ``src/'' directory) for free. We made this change
* in the interest of encouraging the widest possible deployment of
* the technology. The Harvest software is really a reference
* implementation of a set of protocols and formats, some of which
* we intend to standardize. We encourage commercial
* re-implementations of code complying to this set of standards.
