Copyrights
==========

  This section has instructions for SLIB authors regarding copyrights.

  Each package in SLIB must either be in the public domain, or come
with a statement of terms permitting users to copy, redistribute and
modify it.  The comments at the beginning of `require.scm' and
`macwork.scm' illustrate copyright and appropriate terms.

  If your code or changes amount to less than about 10 lines, you do not
need to add your copyright or send a disclaimer.

Putting code into the Public Domain
-----------------------------------

  In order to put code in the public domain you should sign a copyright
disclaimer and send it to the SLIB maintainer.  Contact agj @
alum.mit.edu for the address to mail the disclaimer to.

     I, NAME, hereby affirm that I have placed the software package
     NAME in the public domain.

     I affirm that I am the sole author and sole copyright holder for
     the software package, that I have the right to place this software
     package in the public domain, and that I will do nothing to
     undermine this status in the future.

                                                     SIGNATURE AND DATE

  This wording assumes that you are the sole author.  If you are not the
sole author, the wording needs to be different.  If you don't want to be
bothered with sending a letter every time you release or modify a
module, make your letter say that it also applies to your future
revisions of that module.

  Make sure no employer has any claim to the copyright on the work you
are submitting.  If there is any doubt, create a copyright disclaimer
and have your employer sign it.  Mail the signed disclaimer to the SLIB
maintainer.  Contact agj @ alum.mit.edu for the address to mail the
disclaimer to.  An example disclaimer follows.

Explicit copying terms
----------------------

If you submit more than about 10 lines of code which you are not placing
into the Public Domain (by sending me a disclaimer) you need to:

   * Arrange that your name appears in a copyright line for the
     appropriate year.   Multiple copyright lines are acceptable.

   * With your copyright line, specify any terms you require to be
     different from those already in the file.

   * Make sure no employer has any claim to the copyright on the work
     you are submitting.  If there is any doubt, create a copyright
     disclaimer and have your employer sign it.  Mail the signed
     disclaim to the SLIB maintainer.  Contact agj @ alum.mit.edu for
     the address to mail the disclaimer to.

Example: Company Copyright Disclaimer
-------------------------------------

  This disclaimer should be signed by a vice president or general
manager of the company.  If you can't get at them, anyone else
authorized to license out software produced there will do.  Here is a
sample wording:

     EMPLOYER Corporation hereby disclaims all copyright interest in
     the program PROGRAM written by NAME.

     EMPLOYER Corporation affirms that it has no other intellectual
     property interest that would undermine this release, and will do
     nothing to undermine it in the future.

     SIGNATURE AND DATE,
     NAME, TITLE, EMPLOYER Corporation
