- * 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

- * Broker you deploy, as well as in the query result pages. These
- * links are generated automatically by the standard Broker

- * DERIVATIVE WORKS
- *
- * Users may make derivative works from the Harvest software, subject

- * - 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.
