Appendix F: Conditions of Disclosure of Source Code

See next page.

Source code will be disclosed only when absolutely necessary, and in return for signed copies of both the ``Conditions of Use'' form and this ``Disclosure of Source Code'' form. The conditions are required: to protect the copyright of the author(s); to prevent overly high expectations by programmers working with the code; to ensure that beneficial modifications are generally available; and to prevent divergent versions.

truemm truemm truemm truemm

1. I accept that all source code is the copyright of the author(s) and I will not remove the author(s) name from any of the source code nor from the program banner, nor use the code for any other reason (without additional approval).

2. I will not allow access to the source code to any third party, nor copy it to any computer system other than the one(s) listed above.

3. I will not allow use of the program by any user who has not signed the ``Conditions of Use'' form.

4. I will ensure that users of the program are given adequate access to the available documentation. (The documentation may be reproduced and distributed to users who sign the ``Conditions of Use'' form.)

5. I undertake to answer users questions and will try to solve their problems of usage to the maximum of my ability, without recourse to the author(s), except when absolutely necessary.

6. I accept that both the form (subroutine/procedure names and arguments) and the functionality of the source code may change in future versions.

7. I accept that even after any ``minor'' modification(s) the source code or documentation remains the complete intellectual copyright of the original author(s), and I undertake to send to the author(s) (preferably by e-mail) an example of all ``minor'' modifications. ``Minor'' modifications which may be made are:
   • Changes required to overcome compilation errors or warnings
   • Changes required to overcome errors in the data processing
   • Changes to the default choices offered by FIT2D.
   • Correction of inaccurate documentation.

8. I will not make any ``major'' modifications. (Except under the circumstances of an additional agreement.) ``Major'' modification means any modification not defined as ``minor''.

9. I will allow executable version(s) to be copied to the ESRF for general availability to the academic community under the ``Conditions of Use'' conditions.
