This section describes the terms under which these programs may be freely distributed.
DISTRIBUTION
You may give out free copies of this software subject to the fairly unrestrictive conditions in the following section. The only thing I ask in return for your use of this software is that you send me a postcard, but this is only a request, not a condition for use.
PUBLIC LICENSE
Note: In this and the following sections titled "Copying Policies" and "No Warranty" the terms "this software" and "the software" refer to the source code, compiled object code, and manuals for the programs "ArrayList XFCN", "BinaryTree XFCN", "Research XFCN", "ErrorString XFCN", and "ErrorName XFCN".
I want to make sure that you have the right to give away copies of this software, that you receive source code or else can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To make sure that everyone has such rights, I have to forbid you to deprive anyone else of these rights. For example, if you distribute copies of the software, you must give the recipients all the rights that you have. You must make sure that they receive or can get the source code. And you must tell them their rights (by including this notice).
Also, for my own protection, I must ensure that everyone finds out that there is no warranty for this software. Finally, if any of the software is modified by someone else and passed on, I want its recipients to know that what they have is not what I distributed, so that any problems introduced by others will not reflect on my reputation (each file contains a description of how you should note any changes made to the file).
Therefore I (Ari I. Halberstadt) make the following terms which say what you must do to be allowed to distribute or change the software.
COPYING POLICIES
(1) You may copy and distribute verbatim copies of this software as you receive it, in any medium, provided that you conspicuously and appropriately publish on each file a valid copyright notice ╥Copyright ⌐ 1990 Ari I. Halberstadt╙; keep intact the notices on all files that refer to this License Agreement; and give any other recipients of the software a copy of this License Agreement. You may charge a distribution fee for the physical act of transferring a copy.
(2) You may modify your copy or copies of the software or any portion of it, and copy and distribute such modifications under the terms of Paragraph 1 above, provided that you also do the following:
Ñ cause the modified files to carry prominent notices stating who last changed such files and the date of any change (each source code file contains a header indicating how this is to be done); and
Ñ cause the whole of any work that you distribute or publish, that in whole or in part contains or is a derivative of the software or any part thereof, to be licensed at no charge to all third parties on terms identical to those contained in this License Agreement (except that you may choose to grant more extensive warranty protection to some or all third parties, at your option).
Ñ You may charge a distribution fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
Mere aggregation of other unrelated software with this software (or its derivative) on a volume of storage or distribution medium does not bring the other software under the scope of these terms.
(3) You may copy and distribute the software (or a portion or derivative of it, under Paragraph 2) in machine executable form under the terms of Paragraphs 1 and 2 above provided that you also do one of the following:
Ñ accompany it with the complete corresponding machine-readable source code, and manuals, which must be distributed under the terms of Paragraphs 1 and 2 above; or
Ñ accompany it with the information you received as to where the corresponding source code and manuals may be obtained.
For an executable file, complete source code means all the source code for all modules it contains; but, as a special exception, it need not include source code for modules which are standard libraries that accompany the operating system on which the executable file runs, or which are part of the development environment used to write the software.
(4) You may not copy, sublicense, distribute or transfer the software except as expressly provided under this License Agreement. Any attempt otherwise to copy, sublicense, distribute or transfer the software is void and your rights to use the software under this License Agreement shall be automatically terminated. However, parties who have received computer software programs from you with this License Agreement will not have their licenses terminated so long as such parties remain in full compliance.
(5) If you wish to incorporate parts of the software into other programs whose distribution conditions are different, please write to the author. This license agreement is only intended for general distribution, and I will often agree to different terms.
