The Hitop Licence

Introduction

   This is the licence agreement for the hitop sourcecode. It is closely
   based on the PERL Artistic License.
   
Preamble

   The intent of this document is to state the conditions under which a
   Package may be copied, such that the Copyright Holder maintains some
   semblance of artistic control over the development of the package,
   while giving the users of the package the right to use and distribute
   the Package in a more-or-less customary fashion, plus the right to
   make reasonable modifications.
   
Definitions

   Package refers to the collection of files distributed by the Copyright
   Holder, and derivatives of that collection of files created through
   textual modification.
   
   Standard Version refers to such a Package if it has not been modified,
   or has been modified in accordance with the wishes of the Copyright
   Holder as specified below.
   
   Copyright Holder is [7]David Marshall.
   
   You is you, if you're thinking about copying or distributing this
   Package.
   
   Reasonable copying fee is whatever you can justify on the basis of
   media cost, duplication charges, time of people involved, and so on.
   (You will not be required to justify it to the Copyright Holder, but
   only to the computing community at large as a market that must bear
   the fee.)
   
   Freely Available means that no fee is charged for the item itself,
   though there may be fees involved in handling the item. It also means
   that recipients of the item may redistribute it under the same
   conditions they received it.
    1. You may make and give away verbatim copies of the source form of
       the Standard Version of this Package without restriction, provided
       that you duplicate all of the original copyright notices and
       associated disclaimers.
    2. You may apply bug fixes, portability fixes and other modifications
       derived from the Public Domain or from the Copyright Holder. A
       Package modified in such a way shall still be considered the
       Standard Version.
    3. You may otherwise modify your copy of this Package in any way,
       provided that you insert a prominent notice in each changed file
       stating how and when you changed that file, and provided that you
       do at least ONE of the following:
         a. place your modifications in the Public Domain or otherwise
            make them Freely Available, such as by posting said
            modifications to Usenet or an equivalent medium, or placing
            the modifications on a major archive site such as
            uunet.uu.net. You must also provide those changes to the
            Copyright Holder who may, at their discretion, include your
            modifications in the Standard Version of the Package.
         b. use the modified Package only within your corporation or
            organization.
         c. rename any non-standard executables so the names do not
            conflict with standard executables, which must also be
            provided, provide a separate text file for each non-standard
            executable that clearly documents how it differs from the
            Standard Version. You must also provide those changes to the
            Copyright Holder who may, at their discretion, include your
            modifications in the Standard Version of the Package.
         d. make other distribution arrangements with the Copyright
            Holder.
    4. You may distribute the programs of this Package in object code or
       executable form, provided that you do at least ONE of the
       following:
         a. distribute a Standard Version of the executables and library
            files, together with instructions on where to get the
            Standard Version.
         b. accompany the distribution with the machine-readable source
            of the Package with your modifications.
         c. give non-standard executables non-standard names, and clearly
            document the differences, together with instructions on where
            to get the Standard Version.
         d. make other distribution arrangements with the Copyright
            Holder.
    5. You may charge a reasonable copying fee for any distribution of
       this Package. You may charge any fee you choose for support of
       this Package. You may not charge a fee for this Package itself.
       However, you may distribute this Package in aggregate with other
       (possibly commercial) programs as part of a larger (possibly
       commercial) software distribution provided that you do not
       advertise this Package as a product of your own. You may embed
       this Package's preprocessor within an executable of yours (by
       linking); this shall be construed as a mere form of aggregation,
       provided that the complete Standard Version of the preprocessor is
       so embedded.
    6. The scripts and library files supplied as input to or produced as
       output from the programs of this Package do not automatically fall
       under the copyright of this Package, but belong to whomever
       generated them, and may be sold commercially, and may be
       aggregated with this Package.
    7. C subroutines (or comparably compiled subroutines in other
       languages) supplied by you and linked into this Package in order
       to emulate subroutines and variables of the preprocessor language
       defined by this Package shall not be considered part of this
       Package, but are the equivalent of input as in Paragraph 6,
       provided these subroutines do not change the preprocessor language
       in any way that would cause it to fail the regression tests for
       the language.
    8. Aggregation of this Package with a commercial distribution is
       always permitted provided that the use of this Package is
       embedded; that is, when no overt attempt is made to make this
       Package's interfaces visible to the end user of the commercial
       distribution. Such use shall not be construed as a distribution of
       this Package.
    9. The name of the Copyright Holder may not be used to endorse or
       promote products derived from this software without specific prior
       written permission.
   10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
       IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
       WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR
       PURPOSE.
