The Artistic License
August 15, 1997

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:
        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, or by allowing the
           Copyright Holder to 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, and
           provide a separate manual page for each non-standard executable
           that clearly documents how it differs from the Standard Version.
        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 (in the manual page or
           equivalent) 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 in manual pages (or equivalent),
           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 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.
