### The "Artistic License"

                     The "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 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 whoever 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.

                                     The End
