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 whoever is named in the copyright or
    copyrights for the package.

    "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:

         1. 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, or by allowing the Copyright Holder to include
            your modifications in the Standard Version of the Package.
         2. use the modified Package only within your corporation or
            organization.
         3. rename any non-standard executables so the names do not
            conflict with standard executables, which must also be
            provided, and provide a separate manual page for each
            non-standard executable that clearly documents how it
            differs from the Standard Version.
         4. 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:

         1. distribute a Standard Version of the executables and library
            files, together with instructions (in the manual page or
            equivalent) on where to get the Standard Version.
         2. accompany the distribution with the machine-readable source
            of the Package with your modifications.
         3. give non-standard executables non-standard names, and
            clearly document the differences in manual pages (or
            equivalent), together with instructions on where to get the
            Standard Version.
         4. 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 interpreter 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 interpreter 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. If such scripts or library files are
      aggregated with this Package via the so-called "undump" or
      "unexec" methods of producing a binary executable image, then
      distribution of such an image shall neither be construed as a
      distribution of this Package nor shall it fall under the
      restrictions of Paragraphs 3 and 4, provided that you do not
      represent such an executable image as a Standard Version of 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 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 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.
