8Preamble
9
10This license establishes the terms under which a given free software
11Package may be copied, modified, distributed, and/or redistributed.
12The intent is that the Copyright Holder maintains some artistic
13control over the development of that Package while still keeping the
14Package available as open source and free software.
15
16You are always permitted to make arrangements wholly outside of this
17license directly with the Copyright Holder of a given Package.  If the
18terms of this license do not permit the full use that you propose to
19make of the Package, you should contact the Copyright Holder and seek
20a different licensing arrangement.

74Permissions for Redistribution of the Standard Version
75
76(2)  You may Distribute verbatim copies of the Source form of the
77Standard Version of this Package in any medium without restriction,
78either gratis or for a Distributor Fee, provided that you duplicate

81Compiled form of the Package.
82
83(3)  You may apply any bug fixes, portability changes, and other
84modifications made available from the Copyright Holder.  The resulting
85Package will still be considered the Standard Version, and as such

91(4)  You may Distribute your Modified Version as Source (either gratis
92or for a Distributor Fee, and with or without a Compiled form of the
93Modified Version) provided that you clearly document how it differs
94from the Standard Version, including, but not limited to, documenting
95any non-standard features, executables, or modules, and provided that
96you do at least ONE of the following:
97
98    (a)  make the Modified Version available to the Copyright Holder
99    of the Standard Version, under the Original License, so that the
100    Copyright Holder may include your modifications in the Standard
101    Version.
102
103    (b)  ensure that installation of your Modified Version does not
104    prevent the user installing or running the Standard Version. In
105    addition, the Modified Version must bear a name that is different
106    from the name of the Standard Version.
107
108    (c)  allow anyone who receives a copy of the Modified Version to
109    make the Source form of the Modified Version available to others
110    under
111               
112        (i)  the Original License or
113
114        (ii)  a license that permits the licensee to freely copy,
115        modify and redistribute the Modified Version using the same
116        licensing terms that apply to the copy that the licensee
117        received, and requires that the Source form of the Modified
118        Version, and of any works derived from it, be made freely
119        available in that license fees are prohibited but Distributor
120        Fees are allowed.
121
122
123Distribution of Compiled Forms of the Standard Version
124or Modified Versions without the Source
125
126(5)  You may Distribute Compiled forms of the Standard Version without
127the Source, provided that you include complete instructions on how to
128get the Source of the Standard Version.  Such instructions must be
129valid at the time of your distribution.  If these instructions, at any
130time while you are carrying out such distribution, become invalid, you
131must provide new instructions on demand or cease further distribution.
132If you provide valid instructions or cease distribution within thirty
133days after you become aware that the instructions are invalid, then
134you do not forfeit any of your rights under this license.
135
136(6c9)  You may Distribute a Modified Version in Compiled form without
137the Source, provided that you comply with Section 4 with respect to
138the Source of the Modified Version.

140
141Aggregating or Linking the Package
142
143(7)  You may aggregate the Package (either the Standard Version or
144Modified Version) with other packages and Distribute the resulting
145aggregation provided that you do not charge a licensing fee for the
146Package.  Distributor Fees are permitted, and licensing fees for other
147components in the aggregation are permitted. The terms of this license
148apply to the use and Distribution of the Standard or Modified Versions
149as included in the aggregation.
150
151(8) You are permitted to link Modified and Standard Versions with
152other works, to embed the Package in a larger work of your own, or to
153build stand-alone binary or bytecode versions of applications that
154include the Package, and Distribute the result without restriction,
155provided the result does not expose a direct interface to the Package.
156
157
158Items That are Not Considered Part of a Modified Version
159
160(9) Works (including, but not limited to, modules and scripts) that
161merely extend or make use of the Package, do not, by themselves, cause
162the Package to be a Modified Version.  In addition, such works are not
163considered parts of the Package itself, and are not subject to the
164terms of this license.
165
166
