// GENERAL PUBLIC LICENSE AGREEMENT
// 
// PLEASE READ THIS DOCUMENT CAREFULLY BEFORE UTILIZING THE PROGRAM
// 
// BY UTILIZING THIS PROGRAM, YOU AGREE TO BECOME BOUND BY THE TERMS OF
// THIS LICENSE.  IF YOU DO NOT AGREE TO THE TERMS OF THIS LICENSE, DO
// NOT USE THIS PROGRAM OR ANY PORTION THEREOF IN ANY FORM OR MANNER.
// 
// This Program is licensed, not sold to you by GEORGIA TECH RESEARCH
// CORPORATION ("GTRC"), owner of all code and accompanying documentation
// (hereinafter "Program"), for use only under the terms of this License,
// and GTRC reserves any rights not expressly granted to you.
// 
// 1.  This License allows you to:
// 
// (a) make copies and distribute copies of the Program's source code
// provide that any such copy clearly displays any and all appropriate
// copyright notices and disclaimer of warranty as set forth in Article 5
// and 6 of this License.  All notices that refer to this License and to
// the absence of any warranty must be kept intact at all times.  A copy
// of this License must accompany any and all copies of the Program
// distributed to third parties.
// 
// A fee may be charged to cover the cost associated with the physical
// act of transferring a copy to a third party.  At no time shall the
// program be sold for commercial gain either alone or incorporated with
// other program(s) without entering into a separate agreement with GTRC.
//  
// 
// (b) modify the original copy or copies of the Program or any portion
// thereof ("Modification(s)").  Modifications may be copied and
// distributed under the terms and conditions as set forth above,
// provided the following conditions are met:
// 
//     i) any and all modified files must be affixed with prominent
// notices that you have changed the files and the date that the changes
// occurred.
//              
//     ii) any work that you distribute, publish, or make available, that
// in whole or in part contains portions of the Program or derivative
// work thereof, must be licensed at no charge to all third parties under
// the terms of this License.
// 
//    iii) if the modified program normally reads commands interactively
// when run, you must cause it, when started running for such interactive
// use in the most ordinary way, to display and/or print an announcement
// with all appropriate copyright notices and disclaimer of warranty as
// set forth in Article 5 and 6 of this License to be clearly displayed.
// In addition, you must provide reasonable access to this License to the
// user.
// 
// Any portion of a Modification that can be reasonably considered
// independent of the Program and separate work in and of itself is not
// subject to the terms and conditions set forth in this License as long
// as it is not distributed with the Program or any portion thereof.
// 
// 
// 2. This License further allows you to copy and distribute the Program
//    or a work based on it, as set forth in Article 1 Section b in
//    object code or executable form under the terms of Article 1 above
//    provided that you also either:
// 
//    i) accompany it with complete corresponding machine-readable source
// code, which must be distributed under the terms of Article 1, on a
// medium customarily used for software interchange; or,
// 
//   ii) accompany it with a written offer, valid for no less than three
// (3) years from the time of distribution, to give any third party, for
// no consideration greater than the cost of physical transfer, a
// complete machine-readable copy of the corresponding source code, to be
// distributed under the terms of Article 1 on a medium customarily used
// for software interchange; or,
// 
// 
// 3.  Export Law Assurance.
// 
// You agree that the Software will not be shipped, transferred or
// exported, directly into any country prohibited by the United States
// Export Administration Act and the regulations thereunder nor will be

// 4.  Termination.
// 
// If at anytime you are unable to comply with any portion of this
// License you must immediately cease use of the Program and all
// distribution activities involving the Program or any portion thereof.
//
