    5 			 The "Artistic License"
    6 
    7 				Preamble
    8 
    9 The intent of this document is to state the conditions under which a
   10 Package may be copied, such that the Copyright Holder maintains some
   11 semblance of artistic control over the development of the package,
   12 while giving the users of the package the right to use and distribute
   13 the Package in a more-or-less customary fashion, plus the right to make
   14 reasonable modifications.
   15 
   16 Definitions:
   17 
   18 	"Package" refers to the collection of files distributed by the
   19 	Copyright Holder, and derivatives of that collection of files
   20 	created through textual modification.
   21 
   22 	"Standard Version" refers to such a Package if it has not been
   23 	modified, or has been modified in accordance with the wishes
   24 	of the Copyright Holder as specified below.
   25 
   26 	"Copyright Holder" is whoever is named in the copyright or
   27 	copyrights for the package.
   28 
   29 	"You" is you, if you're thinking about copying or distributing
   30 	this Package.
   31 
   32 	"Reasonable copying fee" is whatever you can justify on the
   33 	basis of media cost, duplication charges, time of people involved,
   34 	and so on.  (You will not be required to justify it to the
   35 	Copyright Holder, but only to the computing community at large
   36 	as a market that must bear the fee.)
   37 
   38 	"Freely Available" means that no fee is charged for the item
   39 	itself, though there may be fees involved in handling the item.
   40 	It also means that recipients of the item may redistribute it
   41 	under the same conditions they received it.
   42 
   43 1. You may make and give away verbatim copies of the source form of the
   44 Standard Version of this Package without restriction, provided that you
   45 duplicate all of the original copyright notices and associated disclaimers.
   46 
   47 2. You may apply bug fixes, portability fixes and other modifications
   48 derived from the Public Domain or from the Copyright Holder.  A Package
   49 modified in such a way shall still be considered the Standard Version.
   50 
   51 3. You may otherwise modify your copy of this Package in any way, provided
   52 that you insert a prominent notice in each changed file stating how and
   53 when you changed that file, and provided that you do at least ONE of the
   54 following:
   55 
   56     a) place your modifications in the Public Domain or otherwise make them
   57     Freely Available, such as by posting said modifications to Usenet or
   58     an equivalent medium, or placing the modifications on a major archive
   59     site such as uunet.uu.net, or by allowing the Copyright Holder to include
   60     your modifications in the Standard Version of the Package.
   61 
   62     b) use the modified Package only within your corporation or organization.
   63 
   64     c) rename any non-standard executables so the names do not conflict
   65     with standard executables, which must also be provided, and provide
   66     a separate manual page for each non-standard executable that clearly
   67     documents how it differs from the Standard Version.
   68 
   69     d) make other distribution arrangements with the Copyright Holder.
   70 
   71 4. You may distribute the programs of this Package in object code or
   72 executable form, provided that you do at least ONE of the following:
   73 
   74     a) distribute a Standard Version of the executables and library files,
   75     together with instructions (in the manual page or equivalent) on where
   76     to get the Standard Version.
   77 
   78     b) accompany the distribution with the machine-readable source of
   79     the Package with your modifications.
   80 
   81     c) give non-standard executables non-standard names, and clearly
   82     document the differences in manual pages (or equivalent), together
   83     with instructions on where to get the Standard Version.
   84 
   85     d) make other distribution arrangements with the Copyright Holder.
   86 
   87 5. You may charge a reasonable copying fee for any distribution of this
   88 Package.  You may charge any fee you choose for support of this
   89 Package.  You may not charge a fee for this Package itself.  However,
   90 you may distribute this Package in aggregate with other (possibly
   91 commercial) programs as part of a larger (possibly commercial) software
   92 distribution provided that you do not advertise this Package as a
   93 product of your own.  You may embed this Package's interpreter within
   94 an executable of yours (by linking); this shall be construed as a mere
   95 form of aggregation, provided that the complete Standard Version of the
   96 interpreter is so embedded.
   97 
   98 6. The scripts and library files supplied as input to or produced as
   99 output from the programs of this Package do not automatically fall
  100 under the copyright of this Package, but belong to whoever generated
  101 them, and may be sold commercially, and may be aggregated with this
  102 Package.  If such scripts or library files are aggregated with this
  103 Package via the so-called "undump" or "unexec" methods of producing a
  104 binary executable image, then distribution of such an image shall
  105 neither be construed as a distribution of this Package nor shall it
  106 fall under the restrictions of Paragraphs 3 and 4, provided that you do
  107 not represent such an executable image as a Standard Version of this
  108 Package.
  109 
  110 7. C subroutines (or comparably compiled subroutines in other
  111 languages) supplied by you and linked into this Package in order to
  112 emulate subroutines and variables of the language defined by this
  113 Package shall not be considered part of this Package, but are the
  114 equivalent of input as in Paragraph 6, provided these subroutines do
  115 not change the language in any way that would cause it to fail the
  116 regression tests for the language.
  117 
  118 8. Aggregation of this Package with a commercial distribution is always
  119 permitted provided that the use of this Package is embedded; that is,
  120 when no overt attempt is made to make this Package's interfaces visible
  121 to the end user of the commercial distribution.  Such use shall not be
  122 construed as a distribution of this Package.
  123 
  124 9. The name of the Copyright Holder may not be used to endorse or promote
  125 products derived from this software without specific prior written permission.
  126 
  127 10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
  128 IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED
  129 WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.
