9
10This copyright license states the terms under which a given free software
11Package may be copied, modified and/or redistributed, while the
12Originator(s) maintain some artistic control over the future development of
13that Package (at least as much artistic control as can be given under
14copyright law while still making the Package open source and free software).
15
16This license is bound by copyright law, and thus it legally applies only to
17works which the copyright holder has permitted copying, distribution or
18modification under the terms of the Artistic License, Version 2.0.
19
20You are reminded that You are always permitted to make arrangements wholly
21outside of a given copyright license directly with the copyright holder(s)
22of a given Package.  If the terms of this license impede your ability to
23make full use of the Package, You are encouraged to contact the copyright
24holder(s) and seek a different licensing arrangement.

27                                Definitions
28
29"Package" refers to the collection of files distributed by the
30          Originator(s), and derivatives of that collection of files created
31          through textual modification.
32
33"Standard Version" refers to the Package if it has not been modified, or has
34                   been modified only in ways suggested by the
35                   Originator(s).
36
37"Modified Version" refers to the Package, if it has been changed by You via
38                   textual modification of the source code, and such changes
39                   were not suggested by the Originator(s).
40
41"Originator"       refers to the author(s) and/or copyright holder(s) of the
42                   Standard Version of the Package.
43
44"You" and "Your" refers to any person who would like to copy, distribute, or
45                 modify the Package.
46
47"Distribution Fee" is any fee that You charge for providing a copy of this
48                   Package to another party.  It does not refer to licensing
49                   fees.
50
51"Freely Available" means that:
52
53       (a) no fee is charged for the right to use the item (though a
54           Distribution Fee may be charged).
55
56       (b) recipients of the item may redistribute it under the same
57           conditions they received it.
58
59       (c) If the item is a binary, object code, bytecode, the complete
60           corresponding machine-readable source code is included with the
61           item.
62
63
64         Permission for Use and Modification Without Redistribution
65
66  (1) You are permitted to use the Standard Version and create and use
67      Modified Versions for any purpose without restriction, provided that
68      you do not redistribute the Modified Version to others outside of your
69      company or organization.
70
71
72           Permissions for Redistribution of the Standard Version
73
74  (2) You may make available verbatim copies of the source code of the
75      Standard Version of this Package in any medium without restriction,
76      either gratis or for a Distribution Fee, provided that you duplicate
77      all of the original copyright notices and associated disclaimers.  At
78      Your discretion, such verbatim copies may or may not include compiled
79      bytecode, object code or binary versions of the corresponding source
80      code in the same medium.
81
82  (3) You may apply any bug fixes, portability changes, and other
83      modifications made available from any of the Originator(s).  The
84      resulting modified Package will still be considered the Standard
85      Version, and may be copied, modified and redistributed under the terms
86      of the original license of the Standard Version as if it were the
87      Standard Version.
88
89
90 Permissions for Redistribution of Modified Versions of the Package as Sour=
91ce
92
93  (4) You may modify your copy of the source code of this Package in any way
94      and distribute that Modified Version (either gratis or for a
95      Distribution Fee, and with or without a corresponding binary, bytecode
96      or object code version of the Modified Version) provided that You
97      clearly indicate what changes You made to the Package, and provided
98      that You do at least ONE of the following:
99
100       (a) make the Modified Version available to the Originator(s) of the
101           Standard Version, under the exact license of the Standard
102           Version, so that the Originator(s) may include your modifications
103           into the Standard Version (at their discretion).
104
105       (b) modify any installation scripts and procedures so that
106           installation of the Modified Version will never conflict with an
107           installation of the Standard Version, include for each program
108           installed by the Modified Version clear documentation describing
109           how it differs from the Standard Version, and rename your
110           Modified Version so that the name is substantially different from
111           the Standard Version.
112
113       (c) permit and encourage anyone who receives a copy of the Modified
114           Version to make your modifications Freely Available in some
115           specific way.
116
117      If Your Modified Version is in turn derived from a Modified Version
118      made by a third party, then You are still required to ensure that Your
119      Modified Version complies with the requirements of this license.
120
121
122      Permissions for Redistribution of Non-Source Versions of Package
123
124  (5) You may distribute binary, object code, bytecode or other non-source
125      versions of the Standard Version of the Package, provided that you
126      include complete instructions on where to get the source code of the
127      Standard Version.  Such instructions must be valid at the time of Your
128      distribution.  If these instructions, at any time while You are
129      carrying our such distribution, become invalid, you must provide new
130      instructions on demand or cease further distribution.  If You cease
131      distribution within thirty days after You become aware that the
132      instructions are invalid, then You do not forfeit any of Your rights
133      under this license.
134
135  (6) You may distribute binary, object code, bytecode or other non-source
136      versions of a Modified Version provided that You do at least ONE of
137      the following:
138
139       (a) include a copy of the corresponding source code for the Modified
140           Version under the terms indicated in (4).
141
142       (b) ensure that the installation of Your non-source Modified Version
143           does not conflict in any way with an installation of the Standard
144           Version, include for each program installed by the Modified
145           Version clear documentation describing how it differs from the
146           Standard Version, and rename your Modified Version so that the
147           name is substantially different from the Standard Version.
148
149       (c) ensure that the Modified Version includes notification of the
150           changes made from the Standard Version, and offer to provide
151           machine-readable source code (under a license that permits making
152           that source code Freely Available) of the Modified Version via
153           mail order.
154
155
156        Permissions for Inclusion of the Package in Aggregate Works
157 =20
158  (7) You may aggregate this Package (either the Standard Version or
159      Modified Version) with other packages and distribute the resulting
160      aggregation provided that You do not charge a licensing fee for the
161      Package.  Distribution Fees are permitted, and licensing fees for
162      other packages in the aggregation are permitted.  Your permission to
163      distribute Standard or Modified Versions of the Package is still
164      subject to the other terms set forth in other sections of this
165      license.
166
167  (8) In addition to the permissions given elsewhere by this license, You
168      are also permitted to link Modified and Standard Versions of this
169      Package with other works and distribute the result without
170      restriction, provided You have produced binary program(s) that do not
171      overtly expose the interfaces of the Package.  This includes
172      permission to embed the Package in a larger work of your own without
173      exposing a direct interface to the Package.  This also includes
174      permission to build stand-alone binary or bytecode versions of your
175      scripts that require the Package, but do not otherwise give the casual
176      user direct access to the Package itself.
177
178
179        Items That are Never Considered Part of a Modified Version Package
180
181  (9) Works (including, but not limited to, subroutines and scripts) that
182      you have linked or aggregated with the Package that merely extend or
183      make use of the Package, but are not intended to cause the Package to
184      operate differently from the Standard Version, do not, by themselves,
185      cause the Package to be a Modified Version.  In addition, such works
186      are not considered parts of the Package itself, and are not bound by
187      the terms of the Package's license.
188
189
190              Acceptance of License and Disclaimer of Warranty
191
192 (10) You are not required to accept this License, since you have not signed
193      it.  However, nothing else grants you permission to copy, modify or
194      distribute the Standard or Modified Versions of the Package.  These
195      actions are prohibited by copyright law if you do not accept this
196      License.  Therefore, by copying, modifying or distributing Standard
197      and Modified Versions of the Package, you indicate your acceptance of
198      the license of the Package.
