13 This is "The Artistic License". It's here so that modules, programs,
14 etc., that want to declare this as their distribution license, can link
15 to it.
16 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 perlgpl.

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