  11  =head1 DESCRIPTION
  12  
  13  This is B<"The Artistic License">. It's here so that modules,
  14  programs, etc., that want to declare this as their distribution
  15  license, can link to it.
  16  
  17  It is also one of the two licenses Perl allows itself to be
  18  redistributed and/or modified; for the other one, the GNU General
  19  Public License, see the L<perlgpl>.
  20  
  21  =head1 The "Artistic License"
  22  
  23  =head2 Preamble
  24  
  25  The intent of this document is to state the conditions under which a
  26  Package may be copied, such that the Copyright Holder maintains some
  27  semblance of artistic control over the development of the package,
  28  while giving the users of the package the right to use and distribute
  29  the Package in a more-or-less customary fashion, plus the right to make
  30  reasonable modifications.
  31  
  32  =head2 Definitions
  33  
  34  =over
  35  
  36  =item "Package"
  37  
  38  refers to the collection of files distributed by the
  39  Copyright Holder, and derivatives of that collection of files created
  40  through textual modification.
  41  
  42  =item "Standard Version"
  43  
  44  refers to such a Package if it has not been
  45  modified, or has been modified in accordance with the wishes of the
  46  Copyright Holder as specified below.
  47  
  48  =item "Copyright Holder"
  49  
  50  is whoever is named in the copyright or
  51  copyrights for the package.
  52  
  53  =item "You"
  54  
  55  is you, if you're thinking about copying or distributing this Package.
  56  
  57  =item "Reasonable copying fee"
  58  
  59  is whatever you can justify on the basis
  60  of media cost, duplication charges, time of people involved, and so on.
  61  (You will not be required to justify it to the Copyright Holder, but
  62  only to the computing community at large as a market that must bear the
  63  fee.)
  64  
  65  =item "Freely Available"
  66  
  67  means that no fee is charged for the item
  68  itself, though there may be fees involved in handling the item. It also
  69  means that recipients of the item may redistribute it under the same
  70  conditions they received it.

  74  =head2 Conditions
  75  
  76  =over
  77  
  78  =item 1.
  79  
  80  You may make and give away verbatim copies of the source form of the
  81  Standard Version of this Package without restriction, provided that you
  82  duplicate all of the original copyright notices and associated disclaimers.
  83  
  84  =item 2.
  85  
  86  You may apply bug fixes, portability fixes and other modifications
  87  derived from the Public Domain or from the Copyright Holder.  A Package
  88  modified in such a way shall still be considered the Standard Version.
  89  
  90  =item 3.
  91  
  92  You may otherwise modify your copy of this Package in any way, provided
  93  that you insert a prominent notice in each changed file stating how and
  94  when you changed that file, and provided that you do at least ONE of the
  95  following:
  96  
  97  =over
  98  
  99  =item a)
 100  
 101  place your modifications in the Public Domain or otherwise make them
 102  Freely Available, such as by posting said modifications to Usenet or an
 103  equivalent medium, or placing the modifications on a major archive site
 104  such as uunet.uu.net, or by allowing the Copyright Holder to include
 105  your modifications in the Standard Version of the Package.
 106  
 107  =item b)
 108  
 109  use the modified Package only within your corporation or organization.
 110  
 111  =item c)
 112  
 113  rename any non-standard executables so the names do not conflict with
 114  standard executables, which must also be provided, and provide a
 115  separate manual page for each non-standard executable that clearly
 116  documents how it differs from the Standard Version.
 117  
 118  =item d)
 119  
 120  make other distribution arrangements with the Copyright Holder.
 121  
 122  =back
 123  
 124  =item 4.
 125  
 126  You may distribute the programs of this Package in object code or
 127  executable form, provided that you do at least ONE of the following:
 128  
 129  =over
 130  
 131  =item a)
 132  
 133  distribute a Standard Version of the executables and library files,
 134  together with instructions (in the manual page or equivalent) on where
 135  to get the Standard Version.
 136  
 137  =item b)
 138  
 139  accompany the distribution with the machine-readable source of the
 140  Package with your modifications.
 141  
 142  =item c)
 143  
 144  give non-standard executables non-standard names, and clearly
 145  document the differences in manual pages (or equivalent), together with
 146  instructions on where to get the Standard Version.
 147  
 148  =item d)
 149  
 150  make other distribution arrangements with the Copyright Holder.
 151  
 152  =back
 153  
 154  =item 5.
 155  
 156  You may charge a reasonable copying fee for any distribution of this
 157  Package.  You may charge any fee you choose for support of this
 158  Package.  You may not charge a fee for this Package itself.  However,
 159  you may distribute this Package in aggregate with other (possibly
 160  commercial) programs as part of a larger (possibly commercial) software
 161  distribution provided that you do not advertise this Package as a
 162  product of your own.  You may embed this Package's interpreter within
 163  an executable of yours (by linking); this shall be construed as a mere
 164  form of aggregation, provided that the complete Standard Version of the
 165  interpreter is so embedded.
 166  
 167  =item 6.
 168  
 169  The scripts and library files supplied as input to or produced as
 170  output from the programs of this Package do not automatically fall
 171  under the copyright of this Package, but belong to whoever generated
 172  them, and may be sold commercially, and may be aggregated with this
 173  Package.  If such scripts or library files are aggregated with this
 174  Package via the so-called "undump" or "unexec" methods of producing a
 175  binary executable image, then distribution of such an image shall
 176  neither be construed as a distribution of this Package nor shall it
 177  fall under the restrictions of Paragraphs 3 and 4, provided that you do
 178  not represent such an executable image as a Standard Version of this
 179  Package.
 180  
 181  =item 7.
 182  
 183  C subroutines (or comparably compiled subroutines in other
 184  languages) supplied by you and linked into this Package in order to
 185  emulate subroutines and variables of the language defined by this
 186  Package shall not be considered part of this Package, but are the
 187  equivalent of input as in Paragraph 6, provided these subroutines do
 188  not change the language in any way that would cause it to fail the
 189  regression tests for the language.
 190  
 191  =item 8.
 192  
 193  Aggregation of this Package with a commercial distribution is always
 194  permitted provided that the use of this Package is embedded; that is,
 195  when no overt attempt is made to make this Package's interfaces visible
 196  to the end user of the commercial distribution.  Such use shall not be
 197  construed as a distribution of this Package.
 198  
 199  =item 9.

 202  products derived from this software without specific prior written permission.
